Questions & Answers

Frequently Asked Questions (FAQs)

Find answers to common technical queries regarding specifications, selection, calibration, and delivery.

Pharma regulations require positive air pressure cascades (e.g. 15 Pa differential) between clean corridors and manufacturing suites to prevent airborne contamination from entering sterile drug areas.

Yes, FGB supplies stainless steel flush mounting wall plates and brackets specifically engineered for cleanroom modular panels.

1 mmWC is approximately equal to 9.81 Pascals. We provide dials calibrated in mmWC, Pascals, or dual scales depending on your plant SOP.
