Every AirZone is individually assembled and calibrated by highly trained operatives to ensure consistent performance. All calibration test equipment is frequently checked to ensure that the highest of standards are met. The scales cover 60-800 L/min.
AirZone PFMs are manufactured to one of two standards; the EU and ATS.
