Engineered specifically for CNC router vacuum hold-down, printing presses, and packaging industries. The KVF250 is a heavy-duty, 100% oil-free dry rotary vane vacuum pump that delivers reliable, continuous suction to keep your materials firmly in place without any oil contamination.
Strong CNC Hold-Down: Delivers a continuous 250 m³/h (147 CFM) and 200 mbar ultimate vacuum, ensuring boards stay securely clamped during high-speed CNC routing.
100% Oil-Free & Clean: Zero oil emissions and no oil changes required. Keeps your workshop clean and eliminates oil maintenance costs.
Long-Lasting Carbon Vanes: Premium self-lubricating carbon vanes provide up to 3,000 hours of continuous, heavy-duty operation.
Plug & Play: Easy installation with low noise, low vibration, and excellent heat dissipation for 24/7 non-stop performance.
The KVF series represents the pinnacle of oil-less, dry rotary vane vacuum technology. Engineered specifically for industries that demand a completely clean, oil-free, and emission-free working environment, such as CNC router vacuum hold-down, printing presses, and food packaging. Unlike traditional oil-sealed pumps, this dry vane pump operates using high-grade, self-lubricating carbon vanes, eliminating the need for oil maintenance and ensuring zero oil-mist exhaust.
Core Advantages:
100% Oil-Free Operation: No oil to check, add, or change. Delivers completely clean exhaust, making it the perfect choice for keeping your CNC workshop or cleanroom spotless.
Powerful CNC Hold-Down: Provides continuous, high-volume suction (up to 250 m³/h / 147 CFM) to ensure MDF, solid wood, and acrylic boards stay securely clamped during high-speed CNC routing.
Extended Carbon Vane Life: Premium self-lubricating carbon vanes provide up to 3,000 hours of continuous operation before requiring a simple, quick replacement.
Low Noise & Low Heat: Optimized internal aerodynamics and improved cooling fans ensure a quiet working environment and excellent heat dissipation.
Plug & Play Maintenance: Simplified structure means fewer moving parts. Routine maintenance is reduced to merely replacing the carbon vanes and periodic bearing lubrication.
Dual units provided for global compatibility.
