Cleanrooms engineered, built & equipped by one factory

Design, materials, equipment and installation supervision in one contract — for food, pharmaceutical, cosmetics and electronics plants. We manufacture the air showers, pass boxes and FFUs ourselves, so projects close 20–40% below typical contractor quotes.

One factory. Four ways to buy.

From a single pass box to a 10,000 m² turnkey plant — every path starts with an engineer, not a salesperson.

Built for your industry's audit

A food plant fails HACCP differently than a pharma plant fails GMP. Pick your industry — the specs, layouts and case studies are already matched to your auditor's checklist.

Why the math favors a factory

We manufacture, not trade

Air showers, pass boxes, FFUs, AHUs, ozone systems — all off our own CNC lines in Zhangzhou.

20–40% lower project cost

Contractors who outsource equipment pay 15–25% more before they even quote you.

Frequently asked questions

Do you install cleanrooms outside China?

Yes. Three models: material package + video guidance; our supervisors leading your local crew (most popular — Vietnam, Thailand, Indonesia, Malaysia, the Philippines); or full turnkey EPC.

What is your minimum order?

Equipment: from 1 unit. Projects: from 100 m² rooms to 10,000 m² plants. Standard equipment ships in 7–15 days.

How do I get a quote?

Send floor plan (a phone photo is fine) or room size, industry, target class and country — engineers return a layout, equipment list and budget within 48 hours, free.

What standards do you build to?

ISO 14644 and GB 50073, meeting GMP and HACCP audit requirements. Third-party particle-count and microbial test reports provided at handover.

Why are your prices 20–40% lower?

We manufacture the air showers, pass boxes, FFUs, AHUs, doors and panels ourselves — contractors who outsource these pay 15–25% more before they even quote you.

How can I verify your factory?

Video factory tour on WhatsApp anytime, or visit us in Zhangzhou, Fujian — one hour from Xiamen international airport.

Can I appoint SGS / BV / TÜV to inspect before shipment?

Yes — third-party pre-shipment inspection at your appointed agency is welcome on every order. We schedule production so inspectors can witness testing.

Do you offer OEM / private label?

Yes — your logo, colors and packaging on ozone generators, air showers and pass boxes, with EPA establishment and ETL/CE certification support. See Wholesale & OEM.
