Pass Through Hatches | Guardware Cleanroom Hardware

Pass-through hatches enhance cleanroom efficiency and contamination control by allowing materials to move between areas without compromising air quality.

Designed with airtight seals and optional interlocks, they minimise cross-contamination risks. Essential for controlled environments across a number of applications, pass-through hatches support regulatory compliance while maintaining sterile, controlled conditions.

ISOpass Max

Grade 304 or 316 active transfer hatch

Wall-mounted design – fixed securely into the cleanroom wall to allow hands-free material transfer between rooms while minimising floor space usage

HEPA-filtered fan filter unit (FFU) – integrated HEPA filtration system actively purges the internal chamber with clean air, removing airborne particles before or during transfer

Mechanical or electro-mechanical interlock system – ensures only one door can be opened at a time, preventing cross-contamination and preserving pressure differentials between clean zones

Flexible, user-centric design – custom dimensions and optional features allow you to de-sign a solution that works best for your process, space and handling needs

ISOpass Pro

Grade 316 or 304 stainless steel passive pass-through hatch

Mechanical door interlock system as standard – prevents both doors from opening simultaneously, ensuring contamination control

Surface-mounted stainless steel hinges – durable, corrosion-resistant and easy to maintain

Optional adjustable support legs – for use when the hatch is not bench-mounted and protrudes from the wall

Custom sizes available – manufactured to suit specific client requirements and structural openings

ISOpass Plus

Sealwise WCB pass-through hatch

Durable yet lightweight – high structural strength with significantly less weight than traditional stainless steel, making handling and installation easier

Seamless installation – delivered with full mounting flanges and optional support legs for quick and clean integration into wall systems

Exceptional hygiene performance – non-porous, seamless surface resists bacterial growth and biofilm formation—ideal for sterile environments

ISOpass Lite

Polypropylene pass-through hatch

Polypropylene construction – durable, lightweight, and highly resistant to a wide range of chemicals and disinfectants

Mechanical or electrical interlock system – prevents both doors from opening simultaneously to preserve pressure differential and prevent contamination

Fully welded interior with radius corners – seamless, crevice-free internal surfaces make cleaning and decontamination easy and effective

Flexible mounting options

Door type options – available with either hinged or sliding doors for space optimisation and workflow convenience

Optional UV or VHP sterilisation

Viewing panels available – optional glazed panels in the doors allow visual inspection of contents without opening the hatch

Custom sizes and configurations – tailored to meet specific cleanroom wall thicknesses, equipment needs and transfer protocols
