With a nominal size of 63 mm and an insertion depth of 32 mm, the A2G-mini differential-pressure gage (photo) has been developed with a view to the E.U. directive for energy-efficient ventilation and air-conditioning systems. Beginning January 1st, 2018, all central units with an air flow of more than 1,000 m³/h must have filter pressure monitoring. The new differential-pressure gage indicates rising pressure loss reliably and in an easily readable format. It is available with four measuring ranges from 0 to 250 Pa to 0 to 1,000 Pa. The pressure gage is completely silicone-free and thus meets the requirements of ISO 846 (microbial metabolic potential). — WIKA Alexander Wiegand SE & Co. KG, Klingenberg, Germany
