Compressed Air Filter Elements
P Grade Pre-Filter Elements
Primary-stage filtration for coarse particles and bulk liquid contaminants in compressed air systems.
Product Description
P Grade Pre-Filter Elements
First-stage compressed air filtration for coarse solids and bulk liquids.
P Grade compressed air pre-filter elements are designed for the primary filtration stage in compressed air systems, removing larger solid particles, pipe scale, rust, and bulk liquid contaminants such as water and oil droplets.
Compressed air entering the filter housing passes through high-efficiency filtration media where contaminants are captured and separated from the airflow. Liquids and larger particles collect at the base of the housing and are removed through a condensate drain.
By removing coarse contaminants at an early stage, P Grade filter elements extend downstream coalescing filter life, improve system reliability, and reduce maintenance costs in staged compressed air treatment systems.

FAQ
FAQ - P Grade Pre-Filter Elements
What is the purpose of a P Grade filter element?
A P Grade filter element removes larger particles such as rust, scale, and solid contaminants from compressed air systems while also capturing bulk liquid droplets.
Where is a P Grade filter typically installed?
It is typically installed as the first filtration stage in a compressed air treatment system, upstream of coalescing or activated carbon filters.
Why is pre-filtration important in compressed air systems?
Pre-filtration removes larger contaminants before the air reaches finer filtration stages, helping protect downstream filters and extend their service life.
Does the P Grade filter remove oil vapours?
No. P Grade filters remove solid particles and bulk liquids, but oil vapours require activated carbon filtration.
How often should P Grade filter elements be replaced?
Replacement intervals depend on system conditions, but elements are typically inspected regularly and replaced during routine compressed air system maintenance.
