Water Master

Firovac also manufacture vacuum tankers, very similar to the Water Master.
The Water Master tanker is a cylindrical unit that uses a rotary vane air displacement pump to create a vacuum for filling. Reversing the pump allows the discharge to be done faster than at normal atmospheric pressure.
The Water Master was invented by Reggie Ridgeway, a former chief fire officer and co-owner of Southern Fire Equipment. The idea for the apparatus came from tankers that the petrochemical companies were using in the 1970's. The pump works the same as a rotary vane primer does for drafting.
The Water Master tanker is available with capacities from 2000 to 4000 gallons. The vacuum pump can maintain a flow rate of 250GPM and the apparatus is also available with a pump up to 1250GPM.
Southern Fire Equipment was acquired by E-One on Apr. 21, 2009. Reggie Ridgeway became the product manager for E-One's Water Master product line. At the time of purchase Southern Fire had manufactured over 300 Water Master units, in use throughout the USA and Canada.
Progress Tank has supplied vacuum tanks and ancilliary equipment to both Southern Fire and E-One for their Water Master products.
