Warping requires air exhausted from over the top of the warp beam through a retractable deflector. The deflector must move out of the way so that string ends can be ‘put up’ on the comb. Air is extracted from plenums on the bottom of the warper creel. Conditioned air is supplied to the warping room through supply air grilles in the ceiling.
Luwa applies the RPF rotary prefilter, the LDF rotary drum filter (or alternately the MCV or APF compact filters) for primary filtration. The FDF Fine Dust Filter and WSA waste separator are applied for waste dust removal and fibre reclaim.
The Luwa Air Washer is applied for controlling temperature and humidity. Luwa B600 axial flow fans are used for primary air movement with Nordfab QF ducting used for distributing air overhead and return air through the hood over the warp beam and form the plenum on the bottom of the creel.
