The Ingersoll Rand 47627050001 22053722 Filter Pad is a flat pre-filter element used in compatible Ingersoll Rand rotary screw compressor intake assemblies. Unlike a cylindrical air filter, this component covers an intake opening and captures coarse airborne contaminants before they reach the main air filter. Its role is to reduce the dust load on downstream filtration and help maintain airflow through the compressor intake enclosure.
In production environments where compressors operate near machining equipment, packaging lines or general workshop activity, airborne dust can accumulate on intake filtration surfaces. A pre-filter pad intercepts part of this contamination before it reaches the main filter element. This can help reduce premature loading of the primary filter, particularly when the compressor runs for extended periods under dusty conditions.
The 22053722 reference is identified as a pre-filter pad for selected Ingersoll Rand compressor packages, including UP5 and EW5 models. The supplied 47627050001 reference should also be retained for product identification. Compatibility must be checked against the installed compressor and intake assembly because a flat pad’s fit depends on the opening, retaining arrangement and required coverage.
During maintenance, technicians should pay attention to the pad’s surface condition and the way it sits in the intake enclosure. A pad that is heavily loaded, torn or incorrectly positioned may either restrict airflow or allow dust to bypass the filtration layer.

When the compressor draws in atmospheric air, the air passes through the pre-filter pad before reaching the main intake filter. The pad retains a portion of the larger airborne particles, including coarse dust and grit, while allowing air to continue through the intake assembly.
As the pad collects contamination, its open passages gradually become obstructed. The resulting increase in airflow resistance can affect the intake conditions and may cause the primary filter to load more quickly if the pre-filter is damaged, missing or no longer performing its intended function.
The pad’s position is as important as its condition. If it is folded, displaced or inadequately retained, incoming air can travel around the filtration material instead of passing through it. This allows contaminants to reach the main filter and can undermine the purpose of the pre-filtration stage.
For maintenance teams, inspection should focus on visible dust accumulation, tears, deformation and the integrity of the retaining arrangement. Replacement should follow the compressor’s service requirements and the condition of the pad. Cleaning or reusing the material should only be done when the applicable maintenance instructions permit it.
The pre-filter pad is not a substitute for the main intake air filter. Both components have separate functions within the intake assembly and should be selected and maintained accordingly.
The filter pad provides an initial barrier against airborne contamination at the compressor intake. It works with the intake grille, housing and main air filter to reduce the amount of particulate matter entering the compression system.

The part reference is associated with selected Ingersoll Rand UP5 and EW5 rotary screw compressor packages. The exact compressor model and intake configuration should be checked before ordering a replacement.
The pad provides an initial filtration stage for coarse airborne contaminants. The main air filter performs the primary intake filtration function. The two components serve different purposes and should not be treated as interchangeable.
Heavy dust accumulation, tears, deformation or displacement can indicate that the pad requires inspection or replacement. Increased intake restriction may also warrant checking the pad alongside the main filter and intake ducting.
That depends on the applicable compressor maintenance instructions and the condition of the filtration material. If the pad is damaged or its permitted service procedure does not allow cleaning, replace it rather than reinstalling it.
