The EC.4 Compact Composites Vacuum Pump is the result of many months of development working 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 to use in vacuum bagging (including prepregs), vacuum bonding, 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 all environments, including manufacturing facilities, workshops, laboratories, schools and universities.

The underlying DVP pump technology is considered to be the best on the market offering an unrivalled combination of performance and reliability - backed by a full manufacturers warranty - whilst the rugged, mobile form factor provides maximum protection and practicality.

Typical Uses

  • Vacuum bagging (including prepregs/autoclave use)
  • Vacuum resin infusion (up to small boat hull size)
  • Vacuum bonding / bag-pressing
  • Vacuum degassing (max 5-10L chamber for more reactive materials)
  • Vacuum casting machines

Advantages

  • Purpose-built composites vacuum pump
  • Designed for continuous duty*
  • Optimised vacuum curve for faster pull-down and ultimate vacuum
  • Smooth, quiet operation
  • No oil mist/vapour
  • Integrated non-return check-valve
  • Compact, lightweight and portable
  • Industrial quality components provide maximum reliability (full spares available)
  • Supported by a full warranty

Which Pump to Choose?

Easy Composites offer two different sizes of industrial quality composites vacuum pump. If you're not sure which one is right for you, here's some advice:

This portable-sized EC.4 Compact Composites Vacuum Pump is recommended for almost all small to medium sized resin infusion, vacuum bagging and vacuum bonding uses. This compact pump would be suitable for use on parts up to the size of a small boat hull (rowing boat, kayak, vehicle panels).

The EC.4 is also suitable for use with small vacuum degassing chambers or with larger chambers when working with less reactive materials such as epoxy and silicone rubber (where a very fast pull-down of the chamber is not necessary).

For very large or multiple vacuum bagging or infusion projects or vacuum degassing operations where a fast pull-down of a large chamber is required then our larger EC.20 Industrial Vacuum Pump is recommended.

Vacuum Degassing

Owing to its optimised vacuum curve, the performance of the EC.4 Compact Composites Vacuum Pump for degassing applications is extremely good meaning that it will start degassing materials much quicker than more conventional vacuum pumps, even when they claim similar or higher 'free air displacement'.

EC.4 is suitable for use with smaller vacuum chambers (up to around 10L) or for use with larger chambers (such as our DC26 Vacuum Degassing Chamber) when working with less reactive materials such as epoxy resin and silicone rubber.

Please note: The EC.4 is NOT suitable for use degassing materials with a high moisture content (such as plaster) or for vacuum drying without the use of a suitable inline moisture trap.

International Use - 220-240v ONLY

The EC.4 vacuum pump is suitable for use in all countries and territories with a 220-240v mains supply. The pump is available with a choice of the most popular international mains plug types. Please choose the plug type you require from the drop-down menu at the top of the page.

This pump cannot be operated on a 110v mains supply such as in the USA or Japan.

Vacuum Pump Oil

The EC.4 Compact Professional Vacuum Pump requires VPO32 Vacuum Pump Oil to run. As supplied, the vacuum pump is empty of oil (to avoid leaking during transport) but is supplied with a bottle of suitable oil. This bottle contains more than sufficient to fill the pump to the correct level.

With suitable precautions, these pumps will run for long periods including overnight. The main consideration is the consumption of oil whilst the pump is under load. The pump must not be allowed to run dry of oil otherwise damage will occur so regularly checking the oil level is a must. If the bag is properly sealed then you will find that the consumption of oil is minimal, in which case the pump will find fine to run overnight without danger of running low or out of oil. On the other hand, if the bag is not properly sealed (i.e. it leaks) then this will put the pump under more load and consume oil much more quickly. In this situation we would not advise leaving the pump unattended.

On the other hand, if the bag is not properly sealed (i.e. it leaks) then this will put the pump under more load and consume oil much more quickly. In this situation we would not advise leaving the pump unattended.

Although these pumps are not designed to have user-serviceable parts, we do have a range of spare parts for professional users or competent persons to replace worn components such as the vanes and some seals which can be arranged by contacting our support department.

The pump is ready to run without any additional accessories required. The pump is fitted with a 1/4 turn vacuum valve and a 'hose tail' barb which is 7mm in OD, making it suitable for both 6mm ID hose and 8mm ID hose. We don't include a vacuum gauge; if you want one then the simplest way would be to get a Male - Female - Male 1/4 BSP 'T Piece'. The male 1/4 BSP thread could screw into the vacuum pump (after you unscrew the existing vacuum valve), the gauge would screw into the female side on the T piece and then the vacuum valve (and barb) could screw back onto the remaining male thread on the T piece. Such a fitting would be available from an air fitting supplier.

Our EC.4 pump is fitted with an inline check valve in the vacuum port of the pump. This means that when the pump is switched off, oil cannot flow back up the vacuum line. For this reason, you do not need a valve on the pump itself.

The EC4 has an inline female 'Shucko' socket on it, the same type of socket that the vast majority of PCs and computer monitors have on them so you'll be using the same type of lead to connect the EC4 to your 220V mains supply. None of the power leads we list on our website are the US convention because not many US customers have access to a 220/240V supply and so we didn't want to cause confusion by offering a US power lead. If you can connect to your 220V system using a standard US 2 pin plug then you can use any PC/monitor power lead you already have.

There are no issues with using this pump with vacuum bagging processes involving vinylester resins.

It is not possible to control or change the level of vacuum the pump achieves directly. The pump is designed to run to a full vacuum only. However it is possible to use a separate SMC vacuum regulator to control the level of vacuum the vacuum bag or chamber connected to the pump achieves. The regulator sits between the pump and the bag/chamber and reduces the level of vacuum to the level set on the regulator's gauge. You can find the SMC vacuum regulator here: SMC Vacuum Regulator

The EC4 is fitted an 8mm hose tail barb which is intended for an 8mm internal diameter hose so your 8mm hose should be a perfect push-fit.

.. and vacuum leak flow indicator. After a prolonged period of running a small amount of oil had backed up in the tubing between the pump and the regulator. Is this normal?



When using the regulator for long periods of time, this is perfectly normal. This is because, in essence, the pump is operating under a load for a prolonged period so you get a very small amount of oil back splatter in the hose. In normal operation, the check valve prevents any significant amount of oil flowing up the inlet pipe when the pump is switched off.

Yes, certainly. This pump is perfectly suited for resin infusion of large car body panels so will have no problem with the panels you describe.

The DVP EC.4 is not designed rated for use with hot air outside the range of normal ambient environmental temperatures. However, for short periods of a couple of minutes or so, it is unlikely that exposure to air at 80°C would cause any long term damage. The oil and pump itself would absorb and dissipate the heat but would then need to cool once switched off.

Yes, connected to a suitable vacuum investment and casting machine, this vacuum pump would be perfectly suitable for supplying the vacuum to the chamber.
