VacAir Superstore supplies, services and repairs vacuum pumps used across the UK composites industry, including aerospace, defence, motorsport, automotive, marine, wind energy, construction, industrial moulding and specialist carbon fibre production.
Whether you need a replacement Becker vacuum pump, Busch vacuum pump, DVP vacuum pump, Elmo Rietschle pump, Leybold pump, urgent breakdown support, spare parts, servicing or advice on a correctly specified vacuum system, we can help keep composite production moving.





Vacuum pumps are used throughout composite manufacturing, from small specialist workshops through to large production facilities producing high value technical components. The correct pump choice depends on the process, mould size, leakage rate, required vacuum level, resin system, duty cycle and whether the pump is expected to run continuously.
We regularly support companies involved in:
Composite parts used in aerospace and defence require consistent production control. Vacuum pumps are used during lay-up, vacuum bagging, resin infusion, bonding, debulking and autoclave preparation.
Stable vacuum helps remove trapped air, consolidate laminate layers and support repeatable results. In these environments, pump reliability and preventative maintenance are essential because failed vacuum can quickly compromise expensive parts, tooling and production time.
Carbon fibre and composite components are widely used in motorsport, performance vehicles and specialist automotive production. Vacuum pumps support moulding, bagging, resin control, trimming fixtures and tooling support.
VacAir has experience supporting demanding industries where downtime is costly and replacement pumps, spare parts and service support need to be available quickly.
Marine composite production can involve large moulds, long vacuum pipe runs and heavy duty operating cycles. Vacuum pumps are used for GRP hull sections, decks, panels, yacht components, interior structures and specialist marine mouldings.
Correct pump sizing is important because large bagged areas and long infusion paths can require both adequate flow and a suitable vacuum level.
Composite manufacturing is also used in wind turbine components, construction products, architectural panels, infrastructure parts, rail, industrial housings and specialist moulded components.
These applications often involve larger parts, production continuity and equipment that needs to be robust, serviceable and correctly maintained.
Vacuum pumps are used throughout composite production to remove air, compress laminate layers, control resin movement, support tooling and maintain a controlled vacuum environment during processing.
Common applications include:
In many composite processes, poor vacuum performance can lead to air inclusions, dry spots, inconsistent resin flow, poor consolidation, increased scrap and avoidable downtime.
The most suitable vacuum pump depends on the process. A pump used for vacuum bagging a small mould may be very different from a pump used on a large resin infusion system, a central vacuum plant or a production hold-down application.
Oil-lubricated rotary vane pumps are commonly used where a deeper vacuum is required. They are often suitable for resin infusion, vacuum bagging, debulking and production processes where strong vacuum performance is important.
Popular examples include Busch R5 pumps, DVP oil-lubricated pumps and Leybold Sogevac style pumps. These pumps require regular oil changes, oil filter replacement, exhaust separator maintenance and inspection for contamination.
Dry running rotary vane pumps are widely used for clean industrial vacuum duties, including vacuum bagging, tooling support, holding applications and composite production where oil-free operation is preferred.
Typical examples include Becker KVT, Becker VTLF, Becker VT and Elmo Rietschle dry vane pumps. These pumps require carbon vane replacement, filter checks and routine servicing.
Claw vacuum pumps are useful for larger industrial duties where dry operation, high flow and reduced routine maintenance are important. They do not use carbon vanes and can be a good option for some production vacuum systems.
DVP claw pumps are often considered for CNC, hold-down and industrial vacuum processes where robust operation and lower maintenance are required.
Side channel blowers are not usually selected where a deep vacuum is required, but they can be suitable for high-flow, low-vacuum duties such as hold-down, air movement, extraction support and some large area handling applications.
Where the application requires a stronger vacuum level, a rotary vane, claw or oil-lubricated vacuum pump is normally more appropriate.
Becker dry running pumps are commonly used for industrial vacuum applications where clean, reliable vacuum is required.
Busch R5 style oil-lubricated pumps are widely used in industrial vacuum applications where a deeper vacuum is required. They are often found in moulding, resin processes, packaging and production environments.
As UK and Ireland Master Agent for DVP Technology, our group can support DVP dry vane, oil-lubricated, claw and side channel blower solutions for composite and industrial applications.
We also support many Elmo Rietschle and Leybold pumps used in composite manufacturing, industrial vacuum and production environments.
Composite production environments can be demanding. Resin vapour, dust, long operating cycles, leaks, blocked filters and neglected servicing can all reduce vacuum performance.
Some of the most common issues we see include:
A gradual or sudden loss of vacuum can cause bagging problems, poor consolidation, resin flow issues, air pockets, rejected parts and production delays.
Common causes include worn vanes, contaminated oil, blocked filters, leaking pipework, split vacuum bags, faulty valves or pump wear.
Oil-lubricated pumps used in resin infusion and composite production can suffer from contaminated oil, especially where vapour, resin contamination or process by-products are pulled towards the pump.
Regular oil changes and filter maintenance are essential to protect the pump and maintain vacuum performance.
Blocked inlet filters reduce flow and can make the pump run hotter. Blocked exhaust separators on oil-lubricated pumps can cause smoking, high back pressure, oil mist problems and poor reliability.
Dry running rotary vane pumps rely on carbon vanes to generate vacuum efficiently. As vanes wear, vacuum performance and flow can reduce. If ignored, worn vanes can eventually break and damage the pump.
We supply replacement carbon vanes for many Becker, Busch, DVP and Elmo Rietschle models used in composite and industrial applications.
A vacuum pump becoming louder than normal or running unusually hot can indicate worn bearings, blocked filters, damaged vanes, poor cooling, contaminated oil or internal wear.
Early intervention can often prevent a major failure and avoid production downtime.
We provide vacuum pump servicing and repairs for composite manufacturers, carbon fibre companies, aerospace suppliers, marine builders, industrial moulders and specialist production sites throughout the UK.
Our services include:
We understand that downtime in composite manufacturing can quickly become expensive, particularly when production involves costly materials, tooling, moulds, resin systems and scheduled cure cycles.
VacAir Superstore supports vacuum pump users across demanding UK industries where reliable production vacuum is critical.
Customers choose us because we offer:
Composite manufacturing can use oil-lubricated rotary vane pumps, dry running rotary vane pumps, claw pumps and side channel blowers, depending on the process. Resin infusion and vacuum bagging often need a stable deeper vacuum, while hold-down and air movement duties may need higher flow.
Yes. VacAir Superstore can supply replacement pumps, service existing pumps and advise on suitable vacuum pumps for resin infusion, vacuum bagging, debulking and composite moulding applications.
Common ca uses include worn vanes, blocked filters, contaminated oil, leaking pipework, damaged bags, pump wear and incorrect pump sizing. These problems can cause poor resin flow, air pockets and production delays.
