EC4 DVP Professional Compact and Portable Quality Oil-Lubricated Vacuum Pump

Professional Compact and Portable Quality Oil-Lubricated Vacuum Pump (EC4 DVP)

Professional quality oil-lubricated vacuum pump in a compact and portable format. EC4 is recommended for most composites applications including resin infusion, prepreg, general vacuum bagging and slower vacuum degassing operations. For prolonged or continuous use, bags/equipment must be properly sealed.

The EC4 Compact Composites Vacuum Pump has been developed in conjunction with leading Italian vacuum pump manufacturer DVP to produce a compact, portable vacuum pump engineered specifically for the rigours of daily use in a composites environment.

The pump is ideally suited for use in vacuum bagging (including prepregs), resin infusion, and vacuum degassing. Despite the small size of this vacuum pump, its optimised vacuum curve and high performance components ensure surprisingly rapid pull-down and attainment of full vacuum.

The pump’s quiet operation, continuous duty cycle, check-valve and virtually mist free operation make it suitable for most environments, including manufacturing facilities, workshops, laboratories, schools and universities.

The underlying DVP pump technology is considered the best on the market, offering an unrivalled combination of performance and reliability, whilst the rugged, mobile form factor provides maximum protection and practicality.

Recommended Uses

• Vacuum bagging prepregs (oven cure or autoclave use)
• Resin infusion
• Smaller vacuum degassing operations
• Resin transfer moulding (RTM/RTM light)
• Vacuum bonding*

EC4 is NOT suitable for prolonged or continuous use in a leaking condition (more than 9 mbar), frequent vacuum degassing of materials with a high water content (such as plaster), or vacuum drying.

Key Features

• Purpose-built composites vacuum pump
• Highest levels of vacuum (99.8% / 2 mbar)
• Zero* oil mist/vapour
• Compact, portable design
• Integrated non-return valve
• Smooth, quiet operation
• Engineered for constant operation* [note below]
• Industrial quality components provide maximum reliability

Further Information

Continuous Operation (Acceptable Levels of Leakage)

EC4 is suitable for continuous operation in conditions where the vacuum bag or equipment are properly sealed, with negligible leaks (range 2―9 mbar). 

*EC4 is not suitable for continuous operation against poorly sealed bags or equipment. Prolonged use in such a condition can overwhelm the pump’s oil vapour recovery system, causing oil leakage and potentially damaging the pump.

Size Capability

Despite its compact size, EC4 offers impressive performance with a free air displacement of >4m³ per hour, ensuring fast pull-down even on large vacuum bags. It is more than capable of vacuum bagging components up to the size of a small boat hull (providing the bag and equipment are properly sealed).

Zero Oil Mist/Vapour

Unlike oil-bath vacuum pumps EC4 features a continuous gas ballast and exhaust mist eliminator to ensure that the exhausted air is almost entirely free from oil making it suitable for use in sensitive environments such as confined workshops, schools, universities and laboratories.

Vacuum Pump Oil

EC4 is an oil lubricated vacuum pump and requires the correct type of oil to run. Oil should be checked and replaced regularly, according to the operating instructions. The pump is already filled with oil and a complimentary bottle of oil will also be supplied for top up, subject to availability at the time of placing your order.

International Use - 220-240V ONLY

EC4 is suitable for use with a 220-240V mains supply and comes with an Australian/New Zealand plug type. This pump cannot be operated on a 110V mains supply such as in the USA or Japan.
