Oil Less Air Compressor With Filter Low Temperature Rise 24H Continuous Running Air Compressor
ARD high-flow two-stage rotary vane vacuum pump is core gas extraction vacuum equipment. It can run independently or work as a backing pump paired with booster pumps, diffusion pumps and molecular pumps for high vacuum systems. Widely used for electronic component manufacturing, vacuum drying, filtration, impregnation, coating, welding, metallurgy and laboratory instruments. This pump works reliably at ambient temperature of 10℃–40℃ with inlet pressure below 10 Torr. Open the gas ballast valve if the relative humidity of pumped gas exceeds 90%.

Key Features and Benefits
Automatic Anti-Backflow Valve
Dual anti-oil backflow design with automatic anti-return valve. It effectively protects your vacuum system and prevents oil contamination of the chamber after shutdown.
Adjustable Gas Ballast
Multi-level gas ballast structure. It adapts to different vacuum requirements and improves the capacity for handling water vapor under humid working conditions.
Integrated Cylinder Block Structure
One-piece cylinder with high machining precision and mature rotary vane technology, bringing consistent performance and high reliability for long continuous operation.
Gear Pump Forced Lubrication
Built-in gear pump and constant-pressure oil supply mechanism for forced lubrication. It maintains steady operation even under high inlet pressure.
Efficient Air Cooling
Air cooling design, no external cold trap required. It reduces installation work and long-term maintenance costs.
Fluororubber Sealing Parts
Fluororubber sealing components enhance corrosion resistance and solve oil leakage problems effectively.
