Ring Blower (4RB620) / Side Channel Blower / Regenerative Blower

Greentech International (Zhangqiu) Co., Ltd is the professional side channel blower supplier. Our revolutionary G_400 blower can create pressure difference of up to 1000mbar-more than any other gas ring pump. So far, the systems used to reach these differential pressure ranges were much louder and larger-or subject to wear. Now the advantage of wearfree operation cupled with a low noise level can also be used in most demanding applications. The G_400 series side channel vacuum pump/compressor can work up to 20, 000 hours without maintenance down time. These specialist machines have proven their reliability under the harshest of conditions. Their noise level was already impressively low, but our engineers and designers are able to make them even more quiet. Features: 1. Beautiful surface 2. Easy installation 3. Low noise level 4. No vibration, and therefore complete dynamic stability 5. Pulsation-free discharge 6. Minimal maintenance 7. Higher pressure ratio 8. Cooler running bearings 9. Longer grease life 10.
