TopAir’s Active Polypropylene Fume Hood is an advanced high-quality system enhanced with innovative technology, offered at highly competitive prices. The hood is made of high-quality non-corrosive polypropylene with excellent chemical resistance.
The Active Fume Hoods protect laboratory staff from noxious fumes released by acids, dangerous gas, and organic solutions – materials and acids that regular steel hoods may not withstand. Harmful and unpleasant chemical fumes are removed from the controlled environment to facilitate a safe and pleasant work environment. The fume hood channels chemical vapors out of the building using an external fan installed on the roof or an external wall.
The fume hood features a sensor that detects staff standing next to the unit, and accordingly, opens and closes the window automatically. The unit’s fan speed changes according to the open/closed mode of the window, saving substantial energy.
Upon a failure, the interior of the cabinet is lighted up in bright red, so that staff, including people with hearing issues, can easily detect the failure from a distance.
VAV System
TopAir’s reliable VAV (Variable Air Volume) system for fume hoods measures the air velocity using a high-quality sensor. The data is converted to an analog signal that can control a VFD (Variable-Frequency Drive).
The system’s key advantage is its ease of operation: an unskilled worker can easily calibrate, set the alarm and operation set points, and control the system. The VAV system provides a safe energy-saving environment and can upgrade fume hoods to smart, advanced devices. TopAir’s VAV system is provided as a complete installed product
