2 Cylinder Modular Airline Trolley

The Modular Airline Trolley is a durable, ISI-certified respiratory system designed for hazardous IDLH environments or oxygen deficient environment. Capable of supporting one or two users for up to 2.15 hour max, it provides a continuous and fail-safe supply of breathing air. The system works by routing air from high-pressure cylinders through a medium-pressure hose to a Lung Demand Valve (LDV) and full-face mask. Because the heavy air reservoirs are kept on the transportable trolley, the wearer experiences zero weight and bulk. Ideal for confined-space tasks like sewer entry, tank cleaning, and spray painting, it comes with a standard 50-meter hose reel extended to total 100 meter length, high pressure & medium pressure alarm, and have seamless cylinder replacement mechanism.

Salient Features

Modular & Highly Adaptable: Easily configured for one or two users with 2- or 4-cylinder configurations (2 × 6 L, 300 bar steel cylinders or 2/4 × 6.8/9 L, 300 bar carbon fibre composite cylinders).
Extended Reach & Duration: Standard 50 m air supply hose is extendable up to a total length of 100 metres.
Fail-Safe Pneumatics: The first-stage pressure reducer delivers a high flow rate (>600 to 1000 LPM) and is designed to fail in safe mode, ensuring uninterrupted air supply to the Lung Demand Valve (LDV).
Uninterrupted Operation: Pneumatics and cylinder interconnections allow seamless replacement of an exhausted cylinder without interrupting airflow from the active cylinders. Includes provision for plant air intake.
Dual Warning Alarms: Equipped with a high-pressure whistle on the trolley (activates at approximately 55 bar) and a medium-pressure audible alarm at the wearer's end (activates at 3–5 bar) to indicate the end of the main air supply.
Zero User Burden: Eliminates the weight and bulk of carrying cylinders. A flame-retardant belt harness secures the breathing tube, preventing pull on the face mask while allowing unrestricted head movement.
Robust Trolley Design: Welded construction available in corrosion-proof, anti-static coated Mild Steel or SS304. Features two wheels and a built-in hose reel with handle and brake to prevent accidental uncoiling.
Heavy-Duty Fire-Retardant Hose: R6 flexible, anti-static, non-kinking air supply hose.
Face Mask & LDV: First-breath activated positive pressure LDV (tilt valve or balanced piston options) used with the Protect 2005 full-face mask featuring double sealing flaps, 5-point harness, wide-view polycarbonate visor, speech diaphragm, and self-demisting design.
Integrated Monitoring: Includes a luminescent high-pressure gauge for continuous cylinder pressure indication and a medium-pressure gauge for monitoring supplied air pressure.
