  • Enclosed work station for cleaning components
  • Compressed air or deionized water feeds through optional ports for washing parts 
  • Single-pass air enters open-loop glovebox through ULPA filter, removing 0.12 um particles with an efficiency of 99.999%
  • Side access door opens inward to contain process particles
  • Steel side access door lined with elastomer gasket for snug seal
  • High-static pressure, clean-running, brushless DC fan motor
  • Fluorescent light module included

Open side access door with stainless steel LiftLatch and use door handle to push open and pull closed. 

Terra's Ducted Filtration Glovebox is optimal for cleansing manufactured components of contaminating particles and remnants generated from part processing. Optional deionized-water guns or compressed-air blow-off guns are used to remove residual fragments from components. Ambient air entering the glovebox goes through an ULPA filter to protect the parts from exposure to additional contaminants.

A common application that usually requires a cleaning step is additive manufacturing, also known as 3-dimensional (3D) printing. Materials used to create 3D objects include liquids, biologics and powders made of thermoplastics and metal. After "printing" the object's layers, residual matter is purged for safety and product presentation. When using potentially harmful materials, the Ducted Filtration Glovebox can be equipped with an additional ULPA filter in the glovebox exhaust port. A 4-inch-diameter flange connects ducting to an air handler or the building's ventilation system, channeling the air safely away from the area.

The glovebox is made of white polypropylene, with a tempered-glass viewing window. These materials resist damage from common lab chemicals and are easy to disinfect. The right-side access door is opened and closed using Terra's stainless steel LiftLatch™; a smaller handle allows personnel to push the door inward, or pull it closed for latching. The windowless door is sturdy and dual-gasketed for maintaining internal environment integrity. A removable gasketed back panel may also be used to introduce larger equipment into the glovebox.

The fan module operates with a high-static pressure, brushless DC motor. Not only does it prevent particle generation, but it also reduces harmful electro-magnetic interferences (EMI) that may damage parts. The energy-efficient motor generates a low noise level of 50 dBA.

Configurations are available for creating a low-humidity cleaning environment in the glovebox. If this is required for your process, an optional port is needed to introduce an inert gas such as nitrogen. Nitrogen or compressed air can also be hooked up to Terra's Ionizing Blow-Off Gun which delivers a precise blast of neutralizing positive and negative ions to targeted surfaces.

Call a Terra Product Specialist to discuss your compressed-gas
or water application needs.

Cleanroom Ionizing Gun

The low input voltage (24 VAC) design eliminates shock hazards to both operators and parts, and a step-down transformer is included for 120VAC power use (220-volt transformer available). It also minimizes EMI (electro-magnetic interference) making it safe for operation around high-precision electronics equipment.
