The B994 is a stiff restore flat sweeping brush. It has a trim of 63mm and a 0.75mm polyester material. It comes in 5 different colours. Available with classic or resin set bristle options. The B994RES version features resin set bristles which offers improved hygiene and bristle retention. The bristles are held in place with stainless steel staples and the holes are then filled with anti-microbial resin. This not only prevents the build up of dirt and grime in the tuft holes, but also the release of filaments into high care manufacturing environments.
