The air filters shall be of the (30%) efficiency Extended Surface type, and shall sewn into a single pocket configuration. The media pocket shall be sewn around a peripheral wire frame assembly to prevent air by-pass, and use a moisture resistant thread to enhance durability.
The filter media shall consist of a non-migrating, dual denier, polyester media, with a needled, single-density, single denier media affixed to the downstream side. Media construction shall provide superior dust holding capacity and arrestance of more than 600 grams and 94% respectively.
Each filter shall have a MERV value of 6, or greater as determined by the A.S.H.R.A.E. 52.2 - 1992 test method, and shall withstand a maximum temperature of 160 o F., and have a minimum burst pressure of 6.0" w.g.
The rated filter face velocity shall be 500 FPM, with an air flow capacity 1750 CFM. The initial resistance shall not exceed 0.24" W.G.
Range: 0-3 in. w.c.
Pressure Limits:10 psi (70 kPa)
Broad ranging in easy to read calibrated increments
Gages ideally suited for general measurements and specific air applications
Compact stationary device, makes it a simple to use tool for pressure measurement applications.
Indicates the restriction on filters and gives a visual indication of when they should be replaced. Red Fluid is a curved inclined-vertical tube manometer that is capable of pressure measurements above and below atmospheric as well as differential pressure measurements. This model offers a range of 0-3 in. w.c. in easy to read calibrated increments.
