MODULAR vacuum system for infusing or vacuum bagging larger composite parts

The MODULAR 2S is a single pump / single resin trap mobile vacuum system for manufacturing composites using processes such as resin infusion and vacuum bagging. The MODULAR 2S is based on a sturdy but light weight mobile docking cart. The bottom level of the cart will accommodate a range of vacuum pumps up to 28 m3/h in capacity with 230 V/50 Hz power, or 12.7 cfm with 115 V/60 Hz power. While there are a number of resin trap lid and vacuum control options for the resin trap on the upper level of the cart, the maximum resin catching capacity is always 12 litres (3.1 US gallons).

MODULAR 2S CoverWhen infusing large parts, the resin trap (complete with vacuum controls) may be removed from the mobile docking cart and remote mounted. Although we recommend having access to at least 2 vacuum systems when infusing resin into large and high value composites, our largest pump capacity MODULAR 2S machine may be used to infuse up to approximately 200 m2 (2,150 ft2) or laminate – as long as the resin overflow can be limited to 12 litres (3.1 US gallons). If this is insufficient, the machine’s resin trap may be used as a manifold for up to 8 supplementary resin traps.

Perfect for both infusers of large parts and new infusers

The large resin catching capacity and the user-friendly controls make the MODULAR 2S the ideal solution for users at both ends of the laminating spectrum. While an excellent machine for experienced laminators infusing large parts, the 2S is the perfect “peace of mind” solution for users new to infusion – where the risk of accidental resin overflow is greater.

Customised from standard modules to meet your needs

The MODULAR 2S is a flexible, module-based machine, able to accommodate a range of vacuum pump sizes, vacuum control and resin trap lid configurations. Considerable opportunity exists to tailor-make a 2S system to suit your specific requirements. The Vacmobile 2S is the ideal choice for laminators searching for a compact, high-performance vacuum system for resin infusion or vacuum bagging.

Vacuum pump 

1 of the following continuous duty single phase oil sealed vacuum pumps:

For 230 V + 5%
  • PVR EM12/B. 50 Hz capacity 12.5 m³/h (7.4 cfm). 60 Hz capacity 15 m³/h (8.8 cfm)
  • PVR EM20/B. 50 Hz capacity 18 m³/h (10.6 cfm). 60 Hz capacity 21.6 m³/h (12.7 cfm)
  • PVR EM28/B. 50 Hz capacity 28 m³/h (16.5 cfm). 60 Hz capacity 33.6 m³/h (19.8 cfm)
For 115 V + 5% 
  • Becker U4.20. 60 Hz capacity 21.6 m³/h (12.7 cfm)
  • PVR EM20/B. 60 Hz capacity 21.6 m³/h (12.7 cfm)

Vacuum level 

Adjustable from approximately 20% vacuum to the pump’s maximum vacuum, as follows: 
  • PVR EM12/B & EM28/B. 20 mbar, 98% vacuum, 15 Torr, 29.3” Hg, -14.4 psi, -99.3 kPa.
  • Becker U4.20 & PVR EM20/B. 10 mbar, 99% vacuum, 8 Torr, 29.6” Hg, -14.55 psi, -100.3 kPa

Resin trap 

  • One RT19 resin trap, with choice of trap lid, control manifold and resin catchpot/degas bucket.

Resin catch pot 

  • 12 litres (3.1 US gallons). Heat resistant to 220 0C (430 0F). Optional polyethylene degas bucket.

Trap lid options 

  • Two lid options are available. One has a shielded glass view port for greater peace of mind when infusing or degassing. The basic trap lid does not have a view port. Refer to Vacmobile RT19 information sheet for details.

Lid connections 

  • Up to 8 connections per lid in 4 optional sizes to suit the following outside diameter extruded tubes: 3/8” to 10 mm, 1/2” to 13 mm, 5/8” to 16 mm, or 19 mm to 3/4”. With adaptors, also suitable for 1/2” and 3/4” inside diameter tubing. On all standard tubing sizes, high integrity vacuum connections are quickly and reliably achieved at the trap lid via O-ring seals on the outside of the tube.

Trap control options 

  • A range of vacuum control options are available. Refer to “Body side port configurations” section of the Vacmobile RT19 information sheet for details.


  • Length: 465 mm (18.3”) 
  • Width: 345 mm (13.6”)
  • Operating height: 1,145 mm (45.1”) 
  • Minimum transport height: 623 mm (24.5”)

Weight range 

  • From 40 kg (88 lbs) with EM12/B pump to 55 kg (121 lbs) with EM28/B pump)


  • Full repair/replacement warranty applicable worldwide
