G2’s Enviropass® stainless steel lead-lined pass-through chamber with lead-lined glass provides protection from radiation.


Lead-lined Pass-Through with Lead-Lined Glass Viewing Windows

G2’s Enviropass® lead-lined pass-throughs with lead-lined glass viewing windows are designed for applications requiring lead-shielding protection, such as those applications requiring protection from radiation.

These double wall pass-throughs are lined with lead and have lead-lined glass viewing windows to protect users and sensitive equipment.

The Enviropass® lead-lined pass-through can be purchased as in-wall units or floor-mounted chambers.

Designed for applications involving radiation within x-ray rooms, radiation therapy rooms and laboratories, our EnviroPass® series of lead-shielded pass-throughs provide protection for technicians.

These double wall pass-throughs are internally lined with 1/16” lead panels to protect users and sensitive equipment from radiation-emitting articles or environments. This model also includes quarter-inch (.25″) thick lead-lined glass viewing ports enabling users to observe materials being transferred through the chamber.

Lead-lined pass-throughs with solid doors and no viewing windows is also available.

Optional features for this pass through include removable shelves, custom wall flanges, custom mounting flanges, and various interlock options.


The EnviroPass® Difference

Pass-through consoles used in hospital, medical, and industrial facilities can be opened and closed dozens or more times daily. EnviroPass® pass-through solutions perform day after day in critical installations. Pass-through failures can bring vital operations to a standstill. EnviroPass® pass-through chambers are built to withstand the rigors of intensive use.

What makes EnviroPass® pass-through transfer chambers the best choice for your pass through requirements?

  • Heavy Duty 16 Gauge Stainless Steel vs. Lighter Duty 18 or 20 Gauge Material
  • Safety Glass Viewing Windows Standard vs. Plastic Windows
  • Heavy Duty Hardware, Hinges, and Latches Standard for Long Service Life
  • Approval Process Prior to Production to Ensure Your Requirements are Met
  • Made in the USA – Work Direct with the Manufacturer, the Experts in Pass-Through Solutions
  • Twenty Years of Service and Support – We’ve Supplied Pass-Through Solutions for Critical Environments since 1999
  • Lifetime Workmanship Guarantee vs. Limited 30 or 90 Day Warranty

These features result in a longer, more reliable service life. Heavier gauge materials vs. the competition results in a much longer duty cycle. Safety glass resists scratches and chemicals better than competition’s standard plastic windows – they are also easier to clean. Our overall build quality and design is trusted and relied upon by biological research facilities, government laboratories, intensive care units, surgical centers, organ transplant facilities, and semiconductor manufacturing plants around the world.
