Two brands, one house
Averinox develops and supplies materials and components; sister brand Spirofil maintains, renovates and optimises the dewatering installations they run in. One owner, one quality system, full product life cycle.

Twenty-five years, told as a revision history.
Engineering drawings improve revision by revision. So did we. Averinox B.V. is a Dutch supplier with over 25 years of experience in woven, sintered and knitted wire mesh, industrial filtration and dewatering solutions, providing responsive support to the petrochemical, food, pharmaceutical and water treatment industries across Europe.

New base in Assendelft, new digital front door, same principles: customised solutions, cost-effective, with minimum downtime — and support that answers.
What we stand on
Certified, since day one
NEN-EN-ISO 9001 and VCA, certified by TÜV — not because the paperwork is fun, but because petrochemical, food and pharma clients should never have to take quality on faith.
Partner, not parts pusher
From material advice and licensor-spec engineering to secondment of engineers and mechanics: we are at our best when we co-design the solution rather than ship a box.
The numbers we are held to
- years of separation engineering experience
- 25+
- dry solid content achieved in dewatering lines
- >80%
- sub-micron filtration with sintered media
- 0.5 µm
- certified by TÜV
- ISO 9001 · VCA
