SILVENT 007-MJ4: with a micro-nozzle for high precision and low energy consumption. By combining the 007 grip's valve construction and a stainless steel micro-nozzle, you can blow exactly the amount of air required. A central hole in combination with surrounding slots makes the nozzle extremely efficient and quiet. Compared with conventional air guns without a nozzle, a SILVENT micro-nozzle permits you to reduce compressed air consumption by up to 75% and, at the same time, keep the noise level under 76 dB(A). The blowing force is approx. 25% of that of a standard gun. Meets the noise limitation requirements of the EU Machine Directive.
