General
Specification
These air filters are suitable for installing on the air intakes of air compressors and air blowers. Three types of filter can be supplied. The dimensions in each case are the same and the elements are interchangeable.
Type SAFS-F
A polyurethane foam element. This easily cleaned porous foam element has a high dust retention capacity and gravimetric efficiency of 96-99 o/o with BS Test Dust No. 2.
Type SAFS-D
A crimped felt element reinforced with expanded aluminium mesh. The filter efficiency is 99 o/o at 4.8 microns.
Type SAFS-P
A knitted polypropylene mesh element. This is a robust unit, suitable for cleaning the air flow where a high degree of filtration is not required.
The silencer section is based on the sound absorption principle. The central duct is wrapped in a protective material to prevent the acoustic filling being drawn into the air stream.
End Connectors
Screwed BSP connectors are fitted to to sizes 6 - 76mm nominal bore (1/4" - 3") and flanges to BS10 Table D on all larger sizes. Different types of flanges or end connectors can be supplied on special quotation.
