MODULAR 4S System

Larger scale MODULAR vacuum system with single and dual vacuum capabilities

Ultimate flexibility: 1 or 2 Vacuum Pumps & 1 or 2 Resin Traps


4S-PDF-Icon
The 4S - the flagship model of the Vacmobile MODULAR Series - is the culmination of more than 25 years’ experience in manufacturing vacuum systems for the fabrication of advanced composites.

Based on a series of interchangeable vacuum pump and resin trap modules, the 4S is a continuous duty vacuum system that is customisable to suit single vacuum level processes such as resin infusion and vacuum bagging over pre-preg and wet laid material, or dual vacuum level processes such as double bag infusion and RTM Light. With an optional interconnection valve on a twin pump / twin resin trap system, interchanging between single or dual vacuum level processes is instantaneous.


Flexible, scaleable….future-proofed

The 4S is a highly flexible and scalable module–based system, housed on a 4-station mobile docking station. The system allows for the simple installation of 1 or 2 vacuum pumps and 1 or 2 resin traps, giving you the freedom to reconfigure the machine to meet the changing needs of your projects.

All modules are extremely easy to install, simply locking into place without the need for tools. When infusing very large parts, the resin trap(s) - complete with vacuum controls - can be removed from the docking station and positioned remotely if required.

Instantaneous switchover from a single vacuum to dual vacuum mode (twin pump/twin trap model).  
 
Valve open:
Both traps operate at same vacuum level.
System can be run on one or two pumps.


4S-detail-7
Valve closed: 
One pump and one trap can operate as a single level vacuum system.
Two pumps and two traps can operate as two independent vacuum systems, e.g., for RTM Light.

Vacuum pump 

1 or 2 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 traps 

  • One or two RT19 resin traps, 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.

Other options 

  • Trap interconnection valve for twin trap machine.

Dimensions 

  • Length: 775 mm (30.5”) 
  • Width: 490 mm (19.3”)
  • Operating height: 1,170 mm (46.1”) 
  • Minimum transport height: 638 mm (25.1”)

Weight range 

  • From 47 kg (103 lbs) to 101 kg (223 lbs), depending on pump and trap combination.

Warranty 

  • Full repair/replacement warranty applicable worldwide.
