Electric Portable Lab Adjustable Speed Vacuum Pump Oil Free Diaphragm Vacuum Pump Oiless Vacuum Pump
VP-30L oilless diaphragm vacuum pump realizes both positive pressure and negative pressure output with a high flow rate of 30 L/min. Featuring clean oil-free air supply, built-in pressure gauge and multi-protection safety design, this portable dual-purpose air source is widely used for laboratory suction filtration, degassing and various pneumatic & vacuum experimental operations.
Features：
💎Dual Positive & Negative Pressure Function
One machine supports both vacuum suction and air pressure output. It can generate max negative vacuum up to 0.085 MPa and max positive pressure of 5.0 bar, satisfying both suction and pressurization needs in experiments.
💎Oil-free Diaphragm Design
No lubricating oil required during operation. It delivers clean, pollution-free air flow, avoiding oil contamination to samples and pipelines.
💎Large Flow Capacity
30 L/min pumping rate enables fast evacuation and pressurization, greatly improving working efficiency for medium and large volume experimental setups.
💎High-precision Built-in Vacuum Gauge
Real-time pressure visual monitoring, allowing users to directly observe pressure status and control experimental conditions conveniently.
💎Premium Imported Rubber Diaphragm Valve
Excellent air tightness, wear resistance and ageing resistance, ensuring stable performance and long service life under continuous operation.
💎Full Safety Protection System
Built-in overload, over-temperature and short-circuit protection modules to prevent motor damage and improve operational safety.
💎Global Wide Voltage Compatibility
AC100–240V universal input voltage, suitable for laboratory power supplies in most countries.
💎Portable Integrated Structure
Equipped with a carrying handle; compact size 240145165mm, easy to transport and place on lab benches.
💎Standard Matching Piping Kit
Supplied with 70cm vacuum tube and standard nozzle size for quick connection with filtration tanks, reactors and other lab equipment.
Applications：
💎Laboratory vacuum filtration, solid-liquid separation and solvent filtration
💎Vacuum degassing and pressure injection of resins, adhesives and liquid samples
💎Pneumatic driving, micro-pressurization and gas transfer operations
💎Environmental testing, chemical synthesis, biological sample pretreatment
💎Teaching experiments in universities and research institutes
💎Food inspection, cosmetic testing and small-scale laboratory extraction
