Keller AmbiTower replaces dirty air with clean air, without ductwork

Keller USA Inc. has introduced the AmbiTower for indirect collection and removal of fine dry, airborne dust and welding fumes. It can collect dirty ambient air and return the clean air back into the workplace without installation of ductwork. This is suitable for processes in which direct capturing at the emission source is not feasible because of equipment location, product size, or process flexibility/requirements.

The unit has a modular design with airflows up to 9,000 CFM and noise level less than 75 dB(A). It includes six self-cleaning filters for 24/7 operation and offers the option of an integrated HEPA stage that allows for air recirculation even when collecting carcinogenic fumes.
