Fast-Vac H-Series™ Hydro Excavator Vacuum Loaders…



are heavy-duty, powerful, efficient, and dust free industrial vacuum modules, integrally mounted on a suitable truck chassis for vacuum removal of virtually any dry material, sludges, slurries, and liquids from remote or inaccessible locations. It is easy to maneuver for a one man operation.  These Hydro Excavators have high demand in the oil field industry, well digging applications, municipal utility location and a wide range of other applications. These units offer a safe, effective alternative to traditional digging equipment.

Each unit can come completely equipped with many options such as the Fast–Vac™ Hydro package including a 270 degree articulating boom. A high-pressure washer system ran by a 3500 P.S.I. Hydraulic Cat Pump. Twin Cylinder body lift, and a Roots style positive displacement 16 Hg or 27 Hg pump. Every Fast-Vac can be mounted on your chassis of choice including Remanufactured units. When the remanufactured units are completed they are zero hour machines.

Bag House and Collector Body Construction

Bag house dumps with the collector body. Easy open/close (no tools required) bag house clean out. Doors are provided on each side of bag house.

Filtration system is of parallel design (versus series design) for more efficient use of available horsepower, thus
eliminating any dusting by utilizing separate flow paths for wet and dry modes. Ladders are provided for access
to all maintenance areas from ground level. Payload capacity is 20 cubic yards (gross) – (16-18 useable) for round bodies and 22
cubic yards (gross) for square bodies.

The safety of the people working with or on Fast-Vac™ equipment is our primary concern. Because of competitive
pressures not to include various safety ideas as standard equipment, Fast-Vac offers all our safety items on all Fast-Vac™ Series models.


Controls in the cab are provided for shifting the transfer case, setting the engine throttle and reverse pulse jet system. Hydraulic controls are located above the truck frame for ease of operation and adequate ground clearance.


Above truck frame mounted instrumentation to be mounted in a NEMA 4 enclosure with safety glass door and will include the following: Differential Pressure Gauge, Vacuum Gauge, Hydraulic Pressure Gauge, Tachometer, Elapsed Time Meter, and Air Pressure Gauge are basic instrumentation.

Hydraulic Dump Hopper

The hopper is constructed of heavy gauge all welded steel construction and is reinforced to handle a negative pressure of 16 Hg with an option of up to 27 Hg.  Hydraulic lift with dual  three-stage cylinders capable of achieving a minimum 50º dump angle. Dual hoist cylinders provide maximum stability while dumping.


Hydraulic over mechanical for open, close, lock, and unlock mechanisms. Heavy Duty D-ring style gasket assures maximum sealing for liquids.


Transmission mounted PTO with hydraulic pump of adequate capacity and pressure rating. Necessary spool  valves and circulation system of adequate pressure and capacity rating.


The safety of the people working with and on this equipment is of primary concern. The following items are included.
A tailgate support and body chock are provided for both tailgate and body when either is in the “UP” position for service work.
All access doors are capable of being locked in the open position.
Changeover from wet to dry mode of operation (and visa versa) is accomplished without entering the machine’s interior.
An audible warning alarm is included in the hydraulic circuit for tailgate open and closed.
Safe (non-skid tape) walking surfaces are provided on all areas of the machine requiring operator or maintenance attention.
All elevated surfaces are enclosed by fold-up hand rails.

All elevated surfaces are enclosed by fold-up hand rails.

All elevated surfaces are enclosed by fold-up hand rails.

A permanently mounted ladder is provided for access to any elevated areas. Ladder starts at ground level.


Unit is designed for ease of maintenance. The unit has a lubrication chart attached. The unit also incorporates commonly manufactured components for ease of replacement of parts and service.


The unit has cleaning access from the top so the unit can be washed down through the bag house, through all inner walls, between the box and the bag house, and all ductwork. There is easy access to wash lower portion of
bag house from side to side and front to rear.


The vacuum module is manufactured with heavy duty industry standard components. The unit is welded by state certified welders to assure the highest quality.
