SR Air System is a leading cleanroom pass box manufacturer specializing in high-quality Dynamic Pass Box and Static Pass Box solutions. Based in Ahmedabad, Gujarat, India, we engineer robust, reliable, and compliant pass-through boxes essential for maintaining contamination control in sensitive environments like pharmaceutical units, laboratories, hospitals, and research facilities.
Minimize the risk of airborne particulates and cross-contamination during material transfer with our range of stainless steel (SS 304/316) pass boxes, built to meet stringent international cleanroom standards.
Static Pass Box Series: Secure Passive Transfer Solutions
The Static Pass Box is the ideal solution for transferring materials between two cleanrooms of the same cleanliness class. It prevents the direct flow of air between rooms through a secure, interlocked door system.
Double Door Static Pass Box
Equipped with a reliable Mechanical Interlocking system to maintain room pressure during transfers
Industrial Static Pass Box
A robust, heavy-duty unit capable of handling material loads up to 100kg.
SS Static Pass Box (Standard)
Features a seamless interior finish with coved corners to prevent dust accumulation.
Stainless Steel Static Hatch Box
A compact, space-saving design ideal for small-scale sampling and glassware transfer.
Pharmaceutical Static Pass Box
Engineered with high-quality silicon gaskets and UV-C lamps for airtight, sterile performance in certified plants.
Dynamic Pass Box Series: High-Sterility Material Transfer
The Dynamic Pass Box functions like a mini-laminar flow unit. It is used for transferring materials between areas of different cleanliness classes (e.g., from a non-sterile area to an ISO Class 5 zone).
Industrial Dynamic Pass Box
Engineered for high-volume manufacturing with reinforced SS 304 construction and high-capacity blowers.
SS Dynamic Pass Box (Standard)
The standard for R&D labs, featuring a fully polished body and coved internal corners for superior hygiene.
Double Door Dynamic Pass Box
Features an advanced Electromagnetic Interlocking system to ensure strict airlock protocols.
FLP (Flameproof) Dynamic Pass Box
Specifically designed for hazardous or volatile environments, equipped with explosion-proof motors and electricals.
Pharmaceutical Dynamic Pass Box
Fully WHO-GMP compliant, featuring Magnehelic pressure gauges and UV-C germicidal sterilization timers.

FAQs
What is the difference between a Dynamic and Static Pass Box?
A Static Pass Box is used for transferring materials between two cleanrooms of equal cleanliness levels. A Dynamic Pass Box acts like an airlock, featuring HEPA-filtered air to decontaminate materials being moved between rooms of different cleanliness levels.
What materials are used in SR Air System Pass Boxes?
Our pass boxes are manufactured using high-quality SS 304 or SS 316 Jindal Stainless Steel, ensuring corrosion resistance and compliance with pharmaceutical hygiene standards.
Do your pass boxes come with an interlocking system?
Yes, all our Dynamic and Static Pass Boxes feature an advanced electromagnetic interlocking system that prevents both doors from opening simultaneously, maintaining the pressure and integrity of the cleanroom.
