HEPA Filters for Pharmaceutical Cleanrooms in South Africa

Pharmaceutical cleanrooms need HEPA filters that come with the right documentation, not just a filter that works, but a filter your compliance team can sign off on. Every Airtech HEPA, H13 and H14, ships with its own serial-numbered test certificate. No chasing paperwork. No batch declarations. The certificate is specific to the unit you install and it is ready for your validation file on delivery. We carry both full-size and half-size HEPA in Pretoria, along with the G4 pre-filters, F9 secondary filters, and F9 V-Bank filters that make up the rest of a typical cleanroom AHU system. One supplier for the full sequence.

Why the EN1822 Test Certificate Matters

EN1822 is the international standard used to test and classify HEPA filters. When your QA team or auditor asks for proof that a HEPA filter meets the required performance, the EN1822 test certificate is the document they are looking for.

Our H13 and H14 HEPA filters are individually tested. Each one gets its own certificate with a serial number. This is different from batch certification, where a sample from a production run is tested and the result is applied to the whole batch. Individual testing means the specific filter installed in your cleanroom has been verified.

The Airtech Filter Range for Pharmaceutical Applications

Pharmaceutical cleanroom air handling typically involves three filtration stages. Each stage has a defined function and a defined certification requirement.

G4 · EN779

Panel Filters

First-stage pre-filtration. Catches coarse dust before it reaches your secondary filters.

View → F9 · EN779

Pocket / Bag Filters

Secondary filtration. The workhorse of the AHU system in cleanroom areas.

View → H14 · EN1822

HEPA Filters

The final filtration stage in the AHU. Individual test certificate included.

View → F9 · EN779

V-Bank Filters

A compact alternative to pocket filters with lower energy consumption. The ABS frame can be incinerated after use, useful where disposal requirements apply.

Common Questions

Which HEPA grade is used for GMP Grade A cleanrooms in South Africa? +
H14 HEPA is commonly specified for Grade A and B areas. H14 means a minimum of 99,995% efficiency at the most penetrating particle size (MPPS). Your specification or validation protocol sets the grade. Every Airtech HEPA filter, H13 and H14 alike, ships with its own serial-numbered EN1822 test certificate for your QA validation file.
Do Prebur HEPA filters come with individual test certificates? +
Yes. Every Airtech HEPA filter supplied by Prebur, H13 and H14 alike, carries a serial-numbered EN1822 test certificate specific to that unit. It records the tested efficiency, resistance and airflow for that filter. Certificates arrive with the delivery and go straight into your QA file, with no separate request.
What is the lead time for H14 HEPA filters from Prebur? +
Prebur holds Airtech H13 and H14 HEPA filters in both full-size (610×610×292mm) and half-size (305×610×292mm) formats in local stock in Silverton, Pretoria. We deliver nationwide by courier, with delivery quoted at checkout, or you can collect. We hold stock for your planned qualification or replacement. Call Nick on +27 74 159 1634 to confirm current stock levels.
Which filter grade is used in GMP Grade B and C cleanroom AHU systems? +
GMP Grade B and C air handling units commonly use F9 pocket or F9 V-Bank filters as the secondary stage ahead of HEPA, with G4 pre-filtration upstream. F9 is rated at ≥95% average efficiency at 0.4µm per EN779:2012. Prebur stocks both F9 pocket filters (595×595×330mm) and the lower-pressure-drop F9 V-Bank format, both manufactured to EN779:2012. Note: per-unit test certificates are supplied with HEPA grades (H13 and H14), not with G4, F9 or other non-HEPA filters.
