Keller Lufttechnik is a pioneer in the field of ATEX compliant dust filter installations. This partner of Lybover AIR has developed its own ATEX-approved back pressure flap, the ProFlap, as a safety component. Our dust filter installations can thus always be protected against dust explosions of both organic dust and metal dust. Also dust filter installations with both an ATEX dust zoning and/or ATEX gas zoning are possible.
