F4 Manufactures Powerful & Efficient Industrial Vacuum Truck Loaders for both Wet & Dry Operations. Vacuum Truck Loaders offer a safe and reliable solution for cleaning up as well as containing Hazardous and Corrosive Liquids. These Vacuum Trucks use High Power Airflow to pneumatically convey Solids, Semi-Solids, Liquids, Sludge and Slurries. The recovred material can be transported safely without any spillage and no environmental hazards for futher processing.

F4 Manufactures Catalyst Handling Filter Units for Wet / Dry Operations in Inert / Ambient conditions with timer Controlled Pulse Jet Air/Nitrogen Blowing System for regular filter cleaning process during Vacuuming Operation. These are specially designed for Filtration of various Catalysts. The Catalyst Filtration Units hold up to aggressive process conditions that include High Temperatures & Pressures, as well as Aggressive or Corrosive Chemistry.

F4 Manufactures High Volume Dry/wet Cyclone Hoppers for the collection and segregation of solid materials during the vacuum operation. Our designs enhance vacuum created by the pump. Continuous suction and intermittent discharge is achieved by Double chamber using alternate discharge flap valves. The valves are pneumatically operated with adjustable timer control unit. Continuous suction and intermittent discharge can also be achieved in single chamber with our Continuous Discharge Valve(CDV)

Nitrogen coming out of roots blower pump absorbes heat from pump that has to be cooled before recirculating it back into the system, we achieve this by passing nitrogen through plate/ tube type heat exchanger. F4 Manufactures plate type and tube type after cooler which can cool nitrogen between 30–40°C.
