Vertical fan is a moveable, 8-ft, high-volume, low-speed fan that can circulate air at up to 38,000 cfm. It employs a 1-hp motor with a gear reducer that can use less than $.05/hr in electricity, on average. The fan uses 10 airfoils to move a massive amount of air at a relatively low speed, producing 5 to 10 times the airflow of standard fans.

Industrial OAM-Purger removes oil, acid, and moisture from a centrifugal chiller's refrigerant charge. The oil is automatically returned to the chiller's oil sump. The clean refrigerant charge restores the chiller to peak efficiency and can have a purger payback of as little as 3 to 4 mo. The purger helps to reduce maintenance and prevent breakdowns.
