Air filter monitor determines element replacement

Filter monitor audits compressed air filters for energy savings by determining the optimal time for element replacement. Through microprocessor monitoring, particulate loading of the filter element is continuously audited based on instantaneous and average daily pressure drop measurements. A 60-day advance notice is given prior to the optimal change-out day. Hankison Intl.; www.hankisonintl.com

Air pressure control saves energy

Pressure control system precisely regulates the low-side compressed air pressure to a field adjustable set point, saving energy costs. A visual indicator and set point pressure display make it simple to set the desired downstream pressure. The display adjusts air pressure automatically to within 2 psig of the desired setting.

Compressed air drain only expels condensate

Eco-Drain removes water from compressed air filters with a capacitance sensor. The sensor has no moving parts and allows the drain to open only when needed, expelling condensate but not valuable compressed air. The robust aluminum housing and superior construction ensure many years of reliable service in harsh environments. Kaeser Compressors; www.kaeser.com
