Floor Swirl Diffuser

The Nailor NFD diffuser is designed for use in raised access floor air distribution systems, where the floor cavity is used as a pressurised supply air plenum.  The NFD core design produces a low velocity helical discharge air pattern.  The design achieves high induction rates of room air which optimises circulation and therefore comfort conditions
