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.

Options and Accessories
Vacuum Pumps (blowers) and Engine Combinations: We offer a wide range of vacuum pumps (blowers) combined with different engines (diesel or gasoline).
High Pressure Water Pump: This feature can be added to most PACS units. The high pressure cold water pump is driven hydraulically from the integral power unit. Water is supplied from a saddle tank mounted on top of the debris tank.
Dry Particulate Filter: Washable polyester filter media rated at 98% efficiency on 10 microns. Molded urethane end caps. Carbon steel core with two support straps. Epoxy coated aluminum back-up wire.
Transfer Pumps:PACS units fitted with auxiliary hydraulic circuits are capable of running a transfer pump. E150 centrifugal pump requires as a minimum, the 25 hp / 18 kW engine. The ES400 helical screw pump requires the 48 hp / 36 kW diesel. These pumps can be used as submersibles for direct pumping.
Oil Skimmers: PACS units fitted with auxiliary hydraulic circuits are capable of running an Elastec drum skimmer such as the TDS118 or TDS136. Skimmed oil is sucked into the debris tank. Alternatively, we can supply a simple floating suction head (ShovelHead skimmer) or SeaSkaterNP suction skimmer.
Rear Door: The PACS unit can be configured with a 36 inch, or fully opening rear door.
