Ultra-Clean Air for Garages, Spray Booths & Food Processing
Connexion Developments’ 3-stage Breathing-Air Filter Regulator Sets deliver technically clean, oil-free, odour-free air for demanding applications: automotive paint spray booths, breathing-air lines, and hygiene-critical production.

Latest Test Results — EN 12021 Compliance Confirmed
In August 2025, our UFR-UMF-UMFB configuration was independently tested and passed a breathing-air quality check. Highlights included:
O₂ 20.65 %, Pressure 6.8 bar, CO = 0, Oil Content: Pass
Dewpoint −8 °C; CO₂ 361 (ppm)
Certificate reference: PM10145/002, completed 29/08/2025, Griffin Air Systems Ltd.
What it means: your spray-booth and breathing-air lines can meet the purity targets expected by EN 12021-style assessments when installed and maintained correctly.
How the 3 Stage Filtration System Works
1) Pre-Filter (5 µm)
Removes bulk water and larger particulates to protect downstream elements.
2) Red Coalescing Filter (0.01 µm)
Captures oil mist and ultra-fine aerosols to achieve oil-free air.
3) Green Activated-Carbon Final Stage (to ~0.003 ppm)
Polishes residual vapours and odours for technically clean air suited to breathing-air use and paint finishing.

Typical Uses
Automotive paint spray booths (HVLP, refinishing, prep bays)
Breathing-air visor/hood lines and maintenance stations
Food & beverage processing lines requiring odour-free, oil-free air
General compressed air filtration before critical processes

Selecting the Right Size (Quick Guide)
Single Booth / Workstation
Choose ¼″–½″ BSP: compact, high-flow performance with minimal footprint.
Multi-Booth / Manifolded Lines
Choose ¾″ or 1″ BSP: higher flow capacity for plant-wide supply.

Care & Compliance Tips
Change elements on time: use the filter-status gauge as your visual trigger.
Log periodic tests: keep EN 12021-style checks on file for audits; our Aug-2025 pass demonstrates the capability when maintained correctly.
Protect upstream: install water separators and drains where needed to extend element life.
FAQs
Are these filter sets suitable for breathing-air applications?
Yes — when installed and maintained correctly. Our configuration passed an independent breathing-air test in Aug-2025 at ~6.8 bar line pressure.
Do you stock replacement elements?
Yes — full element sets and individual 5 µm / 0.01 µm / activated-carbon cartridges are in stock and priced for regular maintenance.
Do smaller port sizes restrict flow?
The ¼″–½″ models offer very similar high flow for single-booth work; step up to ¾″–1″ for multi-booth or manifold supply.
