Sealing cushions with bypass – highly flexible deflection bladders for shutting off and testing
HAAS® sealing cushions with bypass combine the quality and flexibility you need to be able to redirect the wastewater drain during cleaning and renovation work. The wastewater can be diverted in a targeted manner via the film hose and pumped out by a dirty water pump. In addition, the barrier cushions with the foil tube inserted can be easily positioned over an inspection opening. In this way, the operation of the sewage pipes in the household and when using the toilet can continue to be maintained. A quick-release coupling accelerates a secure connection to the compressed air supply. Whether for blocking or redirecting:
The flexible bypass sealing bag solutions from HAAS ® simplify installation and use – and contribute to greater efficiency and safety.
