NASH_elmo ’s G_400 family of gas ring vacuum pumps and compressors operates at pressure differences of up to 1,000 cubic metres an hour.
The pumps offer wear-free operation and low noise emission in applications where much larger and louder systems, or systems subject to extreme wear, were once required. The G_400 pumps and compressors can provide 20,000 maintenance-free operating hours. They are reliable at high or low temperatures, in the tropics, or at sea.
The family significantly reduces the tonal peaks typical of turbo machines. G_400 blowers are comfortably quiet in operation. With a frequency converter installed directly on the motor or in a control cabinet, a machine can generate more power while saving energy. The control systems provide the exact amount of power needed, avoiding excess capacities. The result is a sustained reduction in operating costs.
G_400 pumps and compressors can be installed in any axial orientation. They are easy and economical to install and connect. They are equipped with voltage range motors for 50Hz and 60Hz in protection class IP55 (temperature class F) and are certified to UL 507 and CSA 22.2 no. 113. This means they can be used anywhere in the world.
G_400 pumps and compressors operate without auxiliary materials and are extremely efficient, protecting the environment and reducing costs.
