Pres-Vac offers a selection of portable blowers and sampling covers.
Portable blowers are used to empty a tank of toxic vapour through a water turbine in the blower that creates an air flow, which forces the toxic vapour out of the tank.
Sampling covers allow explosion-safe gas-freeing during voyage. The cover is opened to allow air to escape from the tank. A wire mesh at the opening of the cover prevents flames from entering the tank.
