A modular cleanroom (or portable cleanroom) offers a flexible, cost-effective alternative to traditional "built-in" facilities. Whether you need an ISO 5 micro-environment or an ISO 8 assembly hall, the modular approach allows for rapid deployment and future expansion. At KLC International, w...

While both the Air Shower and the Pass Box are essential for cleanroom contamination control, they serve different masters. The Air Shower is the gatekeeper for personnel, using high-velocity air to "scrub" particles off clothing. The Pass Box is the gatekeeper for materials, allowing for the transf...

Air Changes Per Hour (ACH) is the number of times the entire volume of air in a room is replaced with filtered air within 60 minutes. It is the most critical calculation for achieving and maintaining ISO cleanliness levels. If your ACH is too low, you won't meet your particle count targets. If it's...

Pocket filters (also known as bag filters) are the workhorses of medium-efficiency HVAC filtration. Available in F7, F8, and F9 grades (ISO 16890 ePM1 to ePM2.5), these filters provide high dust-holding capacity and low initial resistance, making them ideal as secondary filters for AHUs and cleanroo...

The Fan Filter Unit (FFU) is the heart of a modular cleanroom. When choosing an FFU, the most critical decision is between an AC motor and an EC (Electronically Commutated) motor. While AC is cheaper upfront, EC motors offer up to 50% energy savings and superior control for large-scale installations...

The ISO 14644-1 standard classifies cleanrooms based on the number of particles per cubic meter of air. Ranging from ISO 1 (the cleanest) to ISO 9, this classification dictates everything from HEPA filter selection to the number of air changes per hour (ACH) required for compliance. Understa...

A laminar flow ceiling is a specialized air distribution system that creates a vertical, unidirectional flow of HEPA-filtered air over the surgical site. By maintaining an ISO 5 environment and positive pressure, it effectively prevents airborne contaminants from entering the surgical wound,...

H13 vs H14 vs U15 vs U16: The Definitive HEPA Efficiency Classification Guide (EN 1822 Data Table) HEPA and ULPA filters are classified by their ability to capture particles at the Most Penetrating Particle Size (MPPS). While H13 (99.95%) is the standard for hospitals, H14 (99.995%) is the b...

Negative pressure rooms prevent the escape of airborne pathogens by maintaining lower air pressure than surrounding areas. The Terminal HEPA Filter Box is the critical engine of this system, filtering exhaust air to ensure no contaminants exit the controlled environment. In high-risk environm...
