General Specifications:

• 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.

• Accuracy:±3% FS

• 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.
