Vacmobile™ Dual-Vac 20
For lite RTM molding, resin infusion and general vacuum bagging

A small machine with impressive performance – single machines have successfully resin infused vacuum bags as large as 185 m² (2,000 ft²).

Primary uses

This dual purpose machine is primarily intended for plants making a mix of small Light RTM parts and virtually any size range of infused parts. With the Dual-Vac accessory fitted, the machine will provide 2 independently controlled vacuum levels – a high vacuum for the clamping flange and a moderate vacuum for the mold region. With the accessory removed, the machine will provide the single vacuum level capabilities of the standard Vacmobile 20/2.

Weight

Approximately 42 kg (93 lbs). Weight varies with pump model.

Vacuum pump

Becker U4.20 or PVR EM 20/B, (PVR EM20 for special high vacuum applications). 50 Hz capacity 18 m³/h (10.6 cfm). 60 Hz capacity 21 m³/h (12.4 cfm).

Vacuum level
(Dual-Vac)

Clamping port: up to the pump’s maximum, typically 10 mbar, 8 Torr, 29.6” Hg, -14.5 psi
Infusion port: adjustable from maximum vacuum to approximately 20% vacuum using zero-loss type membrane regulator valve.

Resin catch pot

2 litres (4.2 US pints). Capacity may be supplemented by external traps, such as the Vacmobile RT19.

Vacuum ports

2 resin trap mounted ports to suit 3/8” – 10mm tubing. High integrity vacuum seals are achieved by means of external O-rings secured by hand-tightened gland nuts. Adapters to other tubing sizes are available.

Power supply

Either 230 V, 50/60 Hz or 110 V, 60 Hz, single phase

Accessories

Vacuum clamping port, complete with dust filter, L-port valve and ¾” male Camlock connection. The L-port valve allows rapid vacuum release and automatic reverse flow filter cleaning in dusty applications.
