Product Overview
49164395 is the intake air filter element for Ingersoll Rand screw air compressors, manufactured to the Donaldson FPG10 specification.
What sets it apart from standard single-stage filters is the two-stage FPG10 design. Air first passes through a built-in tangential pre-cleaner, where high-speed rotation throws coarse particles against the housing wall. About 85% of coarse dust is separated before reaching the main element and is automatically discharged through the Vacuator dust valve at the housing base. Pre-cleaned air then enters the main element for fine filtration through cellulose media. This structure delivers its greatest value in dusty environments: the main element handles only fine particles, maintaining longer service life even under heavy dust loads.
Sealing is also different from conventional filters. The FPG uses Donaldson's RadialSeal technology: an integrally molded polyurethane end cap forms a radial seal directly against the housing outlet tube, eliminating the glued gasket of older axial elements. Fewer parts mean fewer failure points — gasket aging, detachment, and misalignment are eliminated in the FPG design, and installation requires no tools.

Technical Parameters
Filtration Performance
| Parameter | Value / Notes |
|---|---|
| Filtration Rating | 5 μm (main element) |
| Filtration Efficiency | 99.9% (per ISO 5011) |

| Filter Class | Two-stage: centrifugal pre-cleaner + cellulose main element; not classified under EN 779 |
| Dust Holding Capacity | Approx. 1,200 g |
The two-stage design makes a practical difference: a single-stage filter must handle both coarse and fine particles, causing rapid dust buildup on the media, faster pressure rise, and shorter life. By shifting the coarse dust load to the centrifugal pre-cleaner, the FPG10 significantly improves the main element's load profile — which is why it is widely used on construction machinery and generator sets in dusty conditions.
Flow and Pressure Drop
| Parameter | Value / Notes |
|---|---|
| Rated Airflow | ≤346 cfm / 9.8 m³/min (filter assembly rating) |
| Filtration Face Velocity | Approx. 0.038 m/s |
| Initial Pressure Drop | Approx. 0.5–1.0 kPa (approx. 50–100 mmH₂O) |
| Operating Pressure Differential | From new element initial resistance to blockage alarm value |
| Alarm / Final Resistance | Per machine restriction indicator yellow/red zone |
| Pressure Drop vs. Energy | Each 1 kPa increase in intake resistance raises energy consumption by approx. 1% |
Dimensions and Installation
| Parameter | Value / Notes |
|---|---|
| Dimensions | 208 mm OD x 106 mm ID x 409 mm length |
| Configuration | Pleated cylindrical element, two-stage RadialSeal primary element |
| Effective Filtration Area | Approx. 4.3 m² |
| Pleat Count | Approx. 103 pleats |
| Pleat Spacing | Approx. 4.8 mm |
| Installation Interface | Radial push-in; end cap seals against housing outlet tube |
| Sealing | RadialSeal; integrally molded polyurethane end cap forms radial seal, no separate gasket |
| Companion Element | Safety element (inner backup protection) |
Procurement note: When cross-referencing replacements, verify all three dimensions: 208 mm OD, 106 mm ID, and 409 mm length. The FPG design uses radial sealing — push the element in until the end cap contacts the outlet tube. Do not add gaskets; doing so will break the radial seal fit.
Materials of Construction
| Parameter | Value / Notes |
|---|---|
| Media | Cellulose filter paper, per FPG10 specification |
| Media Weight | Approx. 130 g/m² |
| Inner/Outer Support | Galvanized steel perforated cage (inner cage + outer mesh) |
| End Cap | Integrally molded polyurethane (PU) cap encapsulating media ends and sealing surface |
| Seal | RadialSeal formed by PU end cap body; no separate O-ring or gasket |
| Bonding | Molded integrally with end cap; no additional adhesive layer |
Design note: Conventional axial elements use three separate parts — metal end cap, glued gasket, and independent seal ring — and any one aging can cause bypass. The FPG encapsulates the end cap, sealing surface, and media ends in a single polyurethane body, reducing part count and improving seal reliability. This is also what enables tool-free installation.

Installation and Maintenance Steps
A key advantage of the FPG design is tool-free maintenance — each service takes about 15 minutes.
Shut down, verify zero pressure, lock out/tag out. Stop the machine, disconnect main power, and apply lockout/tagout. Criterion: controller shows system pressure at 0.
Open the FPG filter service cover. Release the cover latches — the FPG design uses two spring latches or a twist-off cover, no tools required. Criterion: latches intact, cover not deformed.
Remove the old element. Grip the polyurethane end cap and pull straight out. Criterion: note that the RadialSeal design has no gasket to peel. If you find a residual gasket on the housing outlet tube, a non-genuine part was previously installed and must be cleaned off.
Inspect the Vacuator dust valve. Check the rubber duckbill valve at the housing base. Criterion: valve opens and closes freely, no dust caking, no foreign object blockage. This is the most commonly skipped step in FPG maintenance and has the most serious consequences — a blocked dust valve disables the pre-cleaner, shifting the full dust load to the main element and sharply reducing its life.
Check the pre-cleaner stage and housing for dust traces. Look for dust bypass tracks inside the housing and abnormal accumulation in the pre-cleaner swirl zone. Criterion: no dust tracks on inner walls; if tracks are present, inspect sealing surfaces.
Install the new element. Push the 49164395 into the housing until the polyurethane end cap contacts the outlet tube. Criterion: end cap seats fully against the outlet tube; no gasket is needed or permitted.
Reinstall the service cover and check the restriction indicator. Replace the cover and secure latches. Confirm the intake restriction indicator is in the green zone; if resettable, press to reset and verify it returns properly. Criterion: green zone reading, indicator functions normally.
Start up and record. Start the machine, run to operating temperature, and read intake restriction. Criterion: restriction within new-element baseline range; record date, running hours, and restriction reading.
Installation rule: Do not start the machine before the element is fully seated. If the RadialSeal element is not pushed into place, air will bypass directly through the gap between the end cap and outlet tube, rendering both the pre-cleaner and main element ineffective — equivalent to running without a filter.
Frequently Asked Questions
What specification is the 49164395?
A two-stage RadialSeal primary element manufactured to the Donaldson FPG10 specification. The built-in tangential pre-cleaner removes about 85% of coarse dust first, while the main element handles fine filtration.
Is it interchangeable with 49101637?
No. The 49101637 is FPG09, with different dimensions and rated airflow. Confirmation is simple: read the specification marking on the end cap of the currently installed element. If it reads FPG10, order this part; if it reads FPG09, order 49101637.
Why does this element have no gasket?
Because it uses RadialSeal radial sealing. The polyurethane end cap body forms a seal directly against the housing outlet tube, eliminating the need for a glued gasket or separate seal ring. Fewer parts, fewer failure points, and less chance of incorrect installation.
What does the Vacuator dust valve do?
It is the dust discharge port for the pre-cleaner stage. Coarse dust separated by the swirling airflow falls by gravity to the housing base and is automatically discharged through the Vacuator valve. If the valve becomes blocked, the pre-cleaner is completely disabled and all dust loads the main element directly. Check it at every filter change — this is the critical maintenance action for the FPG design.
How often should it be replaced?
The recommended interval is 2,000 hours or 3 months, whichever comes first. More accurately, follow the intake restriction indicator: replace when resistance enters the yellow zone. In high-dust environments, replace earlier based on indicator readings.
Can the element be blown clean and reused?
No. This is a dry, disposable element. It cannot be washed or reverse-blown with compressed air. Reverse blowing damages the media fiber structure and creates invisible channels that allow unfiltered air to pass — more dangerous than not changing the filter at all.
Can I add a gasket to improve sealing?
No, and it is unnecessary. RadialSeal forms a seal through radial compression of the end cap body. Adding a gasket pushes the element away from the outlet tube, actually breaking the seal fit and causing bypass.
The restriction indicator never moves — is that normal?
No. A stuck indicator is a common failure point and can give a "clean" reading even when the element is actually blocked. Check it at every service by pressing to verify it returns properly. If it has failed, replace the element on a conservative time-based schedule until the indicator is repaired.
What are the pros and cons of the FPG plastic housing versus metal?
The FPG injection-molded housing is corrosion-resistant, lightweight, and vibration-resistant. It will not rust in coastal salt-spray or humid environments, and the tool-free design speeds up field maintenance. This is why the FPG series is widely used on construction machinery and mobile equipment.
How can I be 100% sure this is the right part?
Three steps: ① Read the specification marking on the currently installed element's end cap to confirm FPG10. ② Measure the old part's outer diameter and length to verify 208 mm and 409 mm. ③ If the old part is discarded, provide the model marking on the filter housing, and we will cross-reference by FPG specification.

How to Confirm Compatibility
- Preferred: Read the specification marking on the currently installed element's end cap. If it reads FPG10, this part applies; if FPG09, order 49101637.
- Alternative: Measure the old part's outer diameter and length to verify 208 mm x 409 mm.
- Fallback: Provide the model marking on the filter housing or a photo of the machine nameplate, and we will cross-reference by FPG specification.
Note on Model Coverage
The Donaldson FPG10 is a universal air filter assembly adopted by multiple OEMs, so compatibility is not limited to a specific machine model list. The determining factor is whether the filter specification is FPG10, not the machine model itself. If the machine nameplate does not indicate the filter specification, use any of the three confirmation methods above.
Related Components
The FPG10 filter assembly is a complete system. In addition to the primary element, there are 7 components serviced together with this part. Listed by component — function — inspection point:
| Component | Function | Inspection Point |
|---|---|---|
| Safety Element | Backup element inside the primary element; protects downstream if the primary is damaged or during change intervals | Generally replaced on the same interval or every other change; check media for damage |
| Vacuator Dust Valve | Automatic dust discharge port for the pre-cleaner stage; expels centrifugally separated coarse dust from the housing | Must check at every filter change: valve must open/close freely, no dust caking, no blockage |
| Restriction Indicator | Indicates element blockage level; authoritative basis for replacement timing | Check that the needle returns properly; connecting line must be clear |
| Service Cover and Latches | Tool-free opening/closing structure for the FPG housing | Check latches for cracks, cover for deformation; no air leaks after locking |
| FPG Housing Assembly | Injection-molded plastic housing with tangential inlet and pre-cleaner swirl zone | Check inner walls for dust bypass tracks; check plastic for cracks |
| Intake Hose and Clamps | Connects filter housing to machine intake | Check for cracks, aging, looseness; bypass leakage is as harmful as no filter |
| Other Spec Primary Elements | FPG09; corresponding part number 49101637 | Different dimensions and airflow, not interchangeable; distinguish when stocking |
Companion replacement advice: The maintenance value of the FPG10 system centers on whether the pre-cleaner stage is working properly. When changing the primary element, inspect the Vacuator valve and restriction indicator at the same time. If either small component fails, primary element life is significantly shortened. Their cost is far lower than the primary element, yet they determine how long the primary element lasts.
