General purpose modular air filters remove water and particulate material from the air stream to protect downstream equipment from contamination. As air enters the filter the internal baffles create a swirling motion, so that dirt and liquids are thrown against the side of the filter bowl and then fall into the bottom of the bowl. This model has a manual drain, which is the simplest bowl drain, but they require frequent cleaning to rid the bowl of accumulated water and dirt particles. If a filter is located in a difficult area and can't be accessed to drain frequently, the alternative of an automatic drain would provide an effective way to maximize filter performance and reduce maintenance. Available in 1/8 in. & 1/4 in. port size.

Modular air filters must be cleaned on a regular basis in order to rid them of water and other contaminants. A filter with a manual drain must be removed regularly to remove water so it does not clog the filter. The pressure drop across filter elements increases as they continue to remove dirt from the air. Under average conditions filter elements should be replaced each year.

The plastic bowl on the modular filter is made of tough transparent high-strength polycarbonate. Bowls are intended for use with compressed air, and can be adversely affected if contaminants such as alcohol or liquified petroleum gas are in the intake air. Some compressor oils, solvent fumes and other substance can attack the bowl and lead to failure. To clean the bowl wipe the inside and outside with a clean dry cloth and inspect for cracks or scarring on the surface, if either condition occurs it is an indication that the ambient air contains harmful substances and the bowl should be replaced. Here is a list harmful substances to polycarbonate bowls: acetone, ammonia, benzene, brake fluid, carbon disulfide, carbon tetrachloride, ethyl acetate, ethylene glycol, Freon, lacquer thinner, nitrocellulose lacquer, sodium hydroxide, toluene, turpentine and many others.
