What MONITAIR LIMITED does
Monitair Limited is a UK-based private company, founded in 1989 and headquartered at 19 Albion Street, Hull, England, that designs and manufactures the Chevron, a microprocessor-controlled electronic airflow indicator for Local Exhaust Ventilation (LEV) systems used in industrial, laboratory, and confined-space environments. The Chevron continuously monitors static pressure inside an extract duct and uses a bright orange, moving-chevron display to give an unambiguous visual signal of whether airflow is adequate; firmware variants add dual-alarm operation for spray booths (from serial 1248, June 2016) and a low-power mode extending battery life beyond six years on two AA cells (from serial 2778, July 2017). The device is tamper-proof, weighs 130 g with batteries, can be mounted up to 10 metres from the sampling point, and is calibrated in situ in under 10 seconds using a magnet and LED-guided sequence, eliminating the need to match generic mechanical gauges to specific pressure ranges. Monitair sells exclusively through direct phone (01225 667522) and email contact on a quote-based, hardware-purchase model with no subscription component, targeting UK enterprises that need to comply with HSE HSG258 recommendations; named customers include Enersys (80 units deployed at Newport), Babcock International at Devonport Royal Dockyard, Guernsey Electricity, Imperial College London, and Dawson Construction Plant. The company is bootstrapped and founder-led, operates with 1–10 employees, and has no disclosed revenue, external funding, parent company, subsidiaries, or distribution partners.

MONITAIR LIMITED product offering
Product offeringCore offering
Monitair Limited designs, manufactures, and sells the Chevron Airflow Indicator — a microprocessor-controlled electronic instrument used by industrial and facilities operators to verify and monitor the performance of Local Exhaust Ventilation (LEV) systems. The product is sold directly to UK and international industrial customers that need to confirm their workplace extraction and dust/fume control systems are operating to specification. Related technical resources on LEV examination and commissioning are also offered alongside the hardware.
Product overview
MONITAIR LIMITED offers the Chevron, a single flagship product line of electronic airflow indicators for LEV systems. The core Chevron product monitors static pressure in industrial ventilation ducts to verify proper operation, displayed via a visual chevron indicator. A software variant called Chevron Dual Mode extends functionality for spray booth applications with dual alarm capability. The company also provides associated services including installation guidance and user documentation.

MONITAIR LIMITED competitors and assessment
Company assessmentBroad incumbents
- Honeywell Analytics / Bacharach: Major industrial gas detection and combustion analytics provider serving HVAC and industrial safety. Broad incumbent whose flow/air monitoring instrumentation overlaps with Chevron use cases in commercial and industrial installations.
- CEM Systems (part of Sick AG): Continuous emissions monitoring system (CEMS) provider within Sick AG's industrial environmental portfolio. Broad incumbent in emissions and airflow monitoring at industrial sites, with overlap on LEV and process ventilation compliance applications.
- Airflow Developments: UK manufacturer of fans and ventilation equipment, including airflow measurement and monitoring products for LEV and laboratory fume control. Broad incumbent in the same LEV ecosystem where Monitair's Chevron is deployed.
Direct peers
- TSI Incorporated: US-based precision airflow and particle measurement instrument manufacturer. Comparable as it serves industrial ventilation/laboratory airflow monitoring markets with electronic airflow sensors, often overlapping on fume cupboard and LEV applications.
- Casella: UK-based (and global) manufacturer of industrial air quality, noise, and vibration monitoring instruments. Highly comparable to Monitair in targeting workplace safety monitoring and serving EHS/HSE-compliance use cases; competes for the same UK industrial customers.
- Bion (Trox Bion): US-based manufacturer of airflow measurement and control products including fume hood monitors and LEV airflow sensors. Direct competitor in fume cupboard/LEV airflow monitoring with electronic sensor technology similar to Chevron.
- Degree Controls: Manufacturer of airflow sensing and management products for laboratory fume hoods, biosafety cabinets, and cleanrooms. Directly competes in the same electronic airflow monitoring niche for laboratory enclosures referenced in Monitair's short description.
- AIRFLOW INSTRUMENTS (TSI subsidiary brand): Specialized brand of TSI producing handheld airflow measurement instruments for HVAC/industrial applications. Direct competitor for airflow measurement tools used by EHS and facilities professionals.
Emerging players
- Sensirion: Swiss manufacturer of high-precision MEMS flow and differential pressure sensors. Comparable as a component-level enabler (and potential alternative technology platform) for industrial airflow monitoring devices like Chevron.
Regional players
- Wöhler Technik: German-based manufacturer of measurement and inspection instruments for HVAC, ventilation, and flue gas systems. Comparable LEV/HVAC measurement offerings but primarily serves German-speaking European markets rather than UK.
