Cleanroom Pass-Through Boxes
Cleanroom Pass-Through, All Stainless Steel
Cleatech, your premier provider of advanced cleanroom solutions. Our Double walled Pass-through boxes, Pass-Thrus are constructed from 304 stainless steel essential for maintaining sterile environments while facilitating the safe transfer of materials between different cleanliness zones.
Pass-through boxes also knowsn as pass-through chambers are specialized transfer units designed to minimize contamination during the movement of items between controlled areas. These units act as a barrier, allowing you to transport materials without compromising the cleanliness of your cleanroom or laboratory.

Frequently Asked Questions
1. What is a cleanroom pass-thru air shower?
A cleanroom pass-thru air shower removes particles from materials before transfer, helping maintain cleanliness and reducing contamination risks between controlled environments.
2. Why are pass-thru air showers used in cleanrooms?
They minimize contamination by cleaning surfaces of transferred items, ensuring cleanroom standards are maintained during material movement.
3. How does a pass-thru air shower work?
High-velocity filtered air blows across materials, dislodging particles that are captured through filtration and recirculation systems.
4. What industries use cleanroom pass-thru air showers?
Pharmaceutical, semiconductor, biotechnology, aerospace, medical device, and research facilities commonly use pass-thru air showers.
5. What filters are used in pass-thru air showers?
Most units use HEPA or ULPA filters that efficiently capture airborne particles and contaminants during transfer operations.
6. Can pass-thru air showers improve product quality?
Yes, they reduce contamination on transferred materials, helping protect sensitive products and maintain manufacturing quality standards.
7. Are pass-thru air showers customizable?
Many systems offer customizable sizes, airflow configurations, materials, and control features to meet specific cleanroom requirements.
