Hüdig HC551/35 BigVac - more vacuum, more performance

Based on the very successful HC551/32 Whisper 6", a tuning was carried out, which is known for example in the automotive industry. Long suction lines in combination with unsealed and leaking vacuum systems cause every dewatering system to go to its knees in the long run. The HC551/35 BigVac was developed to counteract an excessive drop in performance and to avoid jeopardizing the success of groundwater lowering.

By redesigning the BigVac rotary vane vacuum pump, it was possible to practically double the air output (from 145m³/h to 280m³/h). This enables the user to successfully operate the HC551/35 BigVac with well over 100 Wellpoint filters. Note: This with a constantly low fuel consumption! At a power output of 50 %, this is approx. 3.5l/h diesel fuel.
