- Vacuums to 27" Hg (914 mbar): The RAM-DVJ provides significantly greater vacuum capability than conventional rotary blowers, helping operators pull material over longer distances, overcome system restrictions, and maintain material flow in challenging recovery applications.
- Flows to 2,367 CFM (4,022 m³/hr): High airflow supports effective conveying performance by generating the air velocity needed to transport liquids, sludge, debris, and waste through the vacuum system and into the tank.
- Continuous High Vacuum Operation: Unlike conventional dry vacuum exhausters that are typically limited to approximately 16" Hg, the RAM-DVJ's integral cooling design permits continuous operation at vacuum levels approaching blank-off with a single-stage machine.
- Simplified Vacuum Technology: With no valves, vanes, or Teflon rings to wear, the RAM-DVJ provides reliable vacuum performance while reducing maintenance concerns associated with other vacuum technologies.
Deep Vacuum Performance for Mobile Vacuum Truck Applications
The ROOTS® RAM-DVJ™ WHISPAIR™ Dry Vacuum Exhauster is engineered for vacuum truck applications requiring higher vacuum levels than conventional rotary blowers can achieve.
Featuring an exclusive discharge jet plenum design, the RAM-DVJ introduces cool atmospheric air into the cylinder to control discharge temperatures, allowing continuous operation at vacuum levels up to 27" Hg with a single-stage unit.
- Continuous operation at high vacuum levels
- No valves, vanes, or Teflon rings to wear
- Exclusive cooling design reduces thermal stress
- Reduced noise and pulsation with WHISPAIR™ technology
- Heavy-duty construction for demanding mobile applications
Delivering up to 2,367 CFM and 27" Hg vacuum, the RAM-DVJ provides the vacuum capability needed for demanding recovery applications where longer hose runs, difficult material pickup, and deeper excavation depths require greater pulling force.
