OEM applications include cabinet air purging, medical respiratory therapy equipment, air samplers, laminar flow hoods, and electronic air cooling systems. As an air filter gage, the Minihelic II finds many end use applications on large stationary engines, compressors, ventilators, and air handling units. Minihelic II gage is suitable for many of the same applications as the Magnehelic gage where the greater accuracy, sensitivity and higher and lower differential pressure ranges of the Magnehelic gage are not required. The standard Minihelic II gage is supplied with two barbed pressure taps molded into the rear housing of the gage. Note the oblong over-pressure vent hole on the back of the gage at the right of connections.
Housing is molded from strong mineral and glass filled nylon.
Pointer stops of molded rubber prevent pointer over-travel without damage. Full view lens is removable and molded of tough polycarbonate. Aluminum scale litho-printed black on white, enhances readability. Red tipped aluminum pointer , rigidly mounted to helix is easy to see. Wishbone assembly provides mounting for helix, helix bearings, and pointer shaft.
