Fixed-Flow Regulator

Product Description

The Fixed-Flow Regulator is purpose-built for the calibration and bump testing of diffusion-based gas detection instruments that draw gas passively rather than by pump. Preset at the factory to a constant delivery rate, typically 0.5 litres per minute, it eliminates the guesswork and human error associated with manually adjusted devices. Technicians simply attach the regulator to a threaded calibration gas cylinder, connect the tubing, and apply gas at a rate the instrument recognises as representative of ambient exposure. The sealed preset mechanism holds output steady from a full cylinder down to near-depletion, protecting the integrity of every calibration record.

Constructed from corrosion-resistant materials suited to reactive and non-reactive gas mixtures, the regulator provides consistent, repeatable performance in workshops, control rooms and remote field locations alike. Its compact, lightweight body makes it ideal for portable calibration kits used across oil and gas terminals, petrochemical plants and utility sites throughout the GCC and India. Because the flow rate cannot drift or be accidentally altered, maintenance teams achieve dependable results while satisfying stringent safety and audit requirements. Filosha Industrial supplies these regulators with cylinder connections matched to common gas standards, backed by responsive regional stock and technical support to keep detector fleets compliant and ready.
