The rugged, trailer mounted PACS vacuum system is purpose-built for removing oil, liquids, solids, and sludge from reclaim pits, catch basins, wastewater lagoons, tank cars, and oil sites. It is available in a variety of blower and vane configurations. It is approved for highway towing (NATM) and can be pulled with a pickup truck, fork truck, tractor, or Multi-Purpose Crawler Carrier. Elastec also manufactures a skid mounted version. The PACS 2000 model can be equipped for hydro-excavation. Read our FAQ.

The trailer-mounted, on/off-road PACS was purpose-built for rough and rugged oil fields to vacuum up water and mud on drilling sites, to clean up oil spills, and to transfer liquids, solids and sludge. PACS was designed to go where large vacuum trucks can’t or for jobs where vac trucks are not cost-effective.

The Elastec PACS is built with heavy-duty components. The extra strong frame is designed to withstand the difficult conditions of remote locations; yet, can be easily towed. The trailer has wide flotation tires and is equipped with safety equipment including surge brakes for highway or off-road towing. The unit is fitted with heavy-duty axles and suspension.

Most models have integral hydraulics that allow the unit to run an oil skimmer, a transfer pump, hydraulic tools, and to lift the spoils tank to dump contents through the rear door. Optional door opening sizes are available. PACS systems are offered with a wide range of accessories. It is fitted with vacuum relief valves and cyclonic separator. A vacuum filter can also be added.

PACS – Skid Mounted Vacuum System

The Skid Mounted PACS (Portable Air Conveyance System) is a high powered vacuum system for a variety of applications – including tank cleaning, sump cleanouts, oil spill recovery, etc.

PACS skid mounted vacuum system
Skid mounted vacuum unit

Shown partially disassembled for shipping. Optional high pressure water pump shown.

The high volume vacuum pump can convey liquids, solids and sludge into the tank, aided by the optional high-pressure water systems (handheld gun with hose reel, fed by the top-mounted water tank).

The unit is equipped with auxiliary hydraulics to run the pressure washer or transfer pump. It can also operate a drum skimmer. (Note: One device at a time)

The tank will elevate (see notes below) approx 15 Degrees when on the ground, to aid emptying. Alternatively, the optional E150 pump can be coupled to the discharge.

This unit is prepared for rigidly mounting on a suitable low profile trailer chassis with sufficient payload and braking.
The unit must be secured to the trailer or the ground before using the tank elevation function. Trailer must remain attached to towing vehicle and supported at the rear.

Frequently Asked Questions

Which type of vacuum pump do I need, Positive Displacement or Rotary Vane?
Our positive displacement vacuum pump is good for moving solids. These pumps typically run 14 to 16 Hg and move more air than the Rotary Vane. The air carries the solids to the tank. The Rotary Vane vacuum pump is good for moving liquids. They typically move less air but have a higher vacuum up to 27 Hg.

Do you have a unit that is good for hydro excavation?
Yes, the PACS 2000 and the PACS 920 have a optional 5 GPM 3000 PSI power washer that works well with the vacuum system for hydro excavation.

Do you have a vacuum unit that is good for moving liquids?
Yes, the PACS 424 has a vane pump and is good to 27 Hg and can pressure unload up to 15 PSI.

Where to buy an Elastec vacuum unit?
You can purchase a vacuum unit from our authorized dealer in your area. If there is no dealer in your area you can purchase straight from the factory.

Is there a lot of maintenance to do on an Elastec vacuum trailer?
There is very little maintenance to do:

  • Check engine oil regularly
  • Check air cleaner regularly
  • Check hydraulic oil level regularly
  • Check oil in blower or vacuum pump regularly
  • Clean sight glasses as needed
  • Open drain valves on moisture trap regularly
  • Change oils and filters per specifications
  • Apply grease at grease points regularly

The PACS vacuum trailer system is ideal for picking up viscous oil and dense solids on land or from water surfaces. It is also very effective for beach cleaning operations that require long suction hoses and large solids handling abilities. The system includes a heavy-duty suction wand, 1,000 gallon / 3.7 cu m tank and a selection of suction hoses. Hydraulics may be used to operate a variety of auxiliary equipment such as skimmers, pumps and pressure washers – see models and figurations below.

A PACS skid mounted unit is available for use with existing vehicles or barges.
