Stainless steel door frames with unique "e" profile elastomer gasket increase structural rigidity, extend service life, improve sealing performance.

Negative Pressure Ventilation Chambers
(Series 200)

• Ideal for drying, degassing, and ventilation applications
  
• Sturdy construction allows sustained negative pressure operation at 5" WG (29.9"Hg in vacuum antechamber)
• Select cylindrical vacuum chamber for higher vacuum levels
• 8" round arm ports accommodate port caps and sleeve/glove combinations

These economical vacuum glove boxes are designed for degassing operations, chemical mixing, biological tests, and other forensic processes requiring sustained negative pressure.

Materials:Acrylic or Polycarbonate
Each chamber is fabricated out of solvent-welded .5" transparent material that combines full visibility with light weight, cleanliness and durability. Dual glove ports allow full access to work in progress. Select acrylic for general applications, or polycarbonate for resistance to a wide range of chemicals and thermal stress.

Equipped with a vacuum safety valve on a standard basis, these chambers are designed for operations with sustained negative pressures down to 5" WG (Water Gauge). All hardware, including latches and hinges, is chrome-plated, and solvent welding ensures a strong, seamless, air-tight structure that won't leak or outgas.

Improved Access Doors Reduce Wear, Enhance Performance
Dual side access doors open inward to allow easy parts transfer from inside the chamber. Doors feature stainless steel reinforcement frames that increase the structural rigidity of the door by a factor of five. A built-in LiftLatch securely seals the door without applying lateral torque that could damage hinges.

All doors include unique, one-piece "e"-profile elastomer gaskets that will not compress or migrate over time. Their superb sealing capability saves nitrogen, eliminates maintenance, and extends the service life of access doors—typically the only component of a glove box that shows wear.

Swing-Up Front Access Panel

Allows convenient introduction of large parts into the processing chamber. Cut-out size: 20"W x 10"H (other sizes available; specify when ordering). See ordering information above.

Versatile Configurations Support Many Negative Pressure Applications
These glove boxes are designed for applications requiring low-level negative pressures, continuous high-volume ventilation, or sustained vacuum at one atmosphere.

By attaching a vacuum pump and vacuum controller, you can dry or degas components at up to 5" WG of negative pressure in either the main chamber or negative pressure air lock. In this application, dual vacuum shut-off valves allow connection to the pump and vacuum bleeding. A safety pressure valve ensures that internal pressure does not exceed 5"WG.

For degassing at one atmosphere (29.9" Hg), select the vacuum antechamber. The pass-through design of this antechamber lets you introduce parts measuring up to 10" x 10" into the glove box for packaging or other processing following vacuum cycling.

Two configurations are available for continuous ventilation of the glove box during soldering, chemical mixing, or other operations that generate noxious fumes. A remote filter/blower module can be connected to the glove box via a 6" flange. Fumes are drawn through the conduit for remote exhausting or vapor removal. Make-up air enters the chamber either through iris glove ports or a HEPA-filtered intake port on top of the box. As an alternative to remote ventilation, a filter/fan unit can be installed directly on top of the glove box. Its ventilation fan draws fumes through a charcoal filter for purification or into an exhaust conduit for remote exhausting. Make-up air enters the chamber through iris glove ports.

Two .5 "-thick plexiglass port caps are included with each Negative Pressure Glove Box to allow the 8" round arm ports to be sealed. These caps are recommended during processes with negative pressure in order to relieve strain on gloves and glove clamps (gloves must be ordered separately).

This application, which supports sustained negative pressure to 5" WG in either the main chamber or the air lock, is ideal for degassing or applications with fuming chemistries.

The Series 200 Glove Box includes dual shutoff valves (for vacuum line and backfill), vacuum gauge and pressure safety switch. Port caps, included with the box on a standard basis, allow the operator to seal the box during negative pressure processing. After bleeding the vacuum, the operator can remove these ports to allow access to the chamber.

A Low-Vacuum Control Module ensures safe, efficient pump operation. The Solenoid vacuum kit includes all vacuum connections required for turnkey operation.

Negative-Pressure Air Lock See above.

Low-Vacuum Control Module
Includes a vacuum gauge with set point control, on/off switches for pump and vacuum solenoid.

Glove Box with Vacuum Service to 29.9" Hg

Like the configuration above, this application supports sustained negative pressure to 5" WG in the Series 200 Glove Box. The addition of a vacuum antechamber allows drying or degassing at up to one full atmosphere (29.9"Hg). This acrylic pass-through antechamber is available in two lengths (12" or 23") and accommodates materials up to 10" x 10".

Glove box and antechamber include dual shutoff valves (for vacuum line and backfill) and a 0 - 30"Hg vacuum gauge. The glove box also features a pressure safety switch and port caps.

A Full-Vacuum Control Module maintains a user-defined pressure level and ensures safe, efficient pump operation. The Solenoid Vacuum Kit includes all vacuum connections required for turnkey operation.

Series 200 Glove Box See above.

Vacuum Antechamber
Made of .5"-thick acrylic, this antechamber safely supports vacuum to 29.9"Hg, making it ideal for degassing, vacuum encapsulation, and vacuum testing. It mounts on the right side of the Series 200 Negative Pressure Glove Box for easy pass-through operation. Includes a vacuum gauge and dual shutoff valves. Price includes installation.

Filter/Blower Module Provides Remote Ventilation

A variety of filters are available to help you meet OSHA and other environmental requirements for exhaust purification. The activated charcoal filter listed below removes most organic chemical vapors to allow safe indoor release. Specialized filters are available for other fumes. HEPA or ULPA particle filters can be used to remove particles as small as 0.12µm.

For particle-sensitive applications, an ULPA-filtered Air Inlet Module is mounted on top of the Series 200 chamber. In this application, an operator uses gloves to access materials inside the chamber.

If particles are not a concern, specify iris ports. These ports, made of multi-layered, self-closing silicone panels, allow make-up air to enter the chamber. Note: in this configuration, port caps cannot be used while the ventilation unit is turned on.

The 14"W x 13.5"D x 32.25"H polypropylene module houses a 740 CFM variable-speed blower that ventilates fumes inside the Series 200 Glove Box. Several filters are available for removal of organic chemical vapors or particles (order separately). All models are 110VAC/60Hz (add "-220" to part number for 220VAC/50Hz).

Series 200 Glove Box with Filter/Blower Module

This module, available in several materials, allows exhaust fumes to be ducted to an in-house exhaust system or purified by an activated charcoal filter for safe release. The versatile filter housing also accommodates a final particle filter (HEPA or ULPA).

Make-up air enters the chamber through iris ports made of multi-layered, self-closing silicone panels. Note: In this configuration, port caps cannot be used while the ventilation unit is turned on.
