Our revolutionary 4BH 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 wear –free operation cupled with a low noise level can also be used in most demanding applications. The 4BH series side channel vacuum pump/compressor can work up to 20000 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.
