Airline - Modulair

Airline breathing apparatus is the perfect solution for applications across many industries. However, the selection of the equipment has traditionally been seen as a complicated process – due to the high number of options available. Aiding this selection process, Scott Health & Safety has over 65 years experience in the manufacture of breathing apparatus, providing unrivalled technical support and advice. With the widest choice of airline breathing solutions, the Company’s Sabre range is internationally renowned for reliability, ease of use, durability and comfort.

Ideal for environments where ambient oxygen cannot be guaranteed, airline breathing apparatus combines the highest degree of respiratory protection with long duration use. Fed by a medium pressure air hose, it is used for industrial applications as diverse as entering sewers, cleaning out tanks and spray painting military aircraft.

The advantages are clear: there is no weight, no bulk and – in theory – an infinite amount of air. Completely modular, Sabre airline components afford almost unlimited flexibility, allowing the user to individually specify a system that exactly meets their operational needs. Multiple configurations can be selected from a standalone portable product – for
use where no other supply of compressed air is available – to products that integrate into existing compressor-fed airline infrastructure.

WHAT TO CONSIDER WHEN SPECIFYING
Before specifying airline breathing apparatus, it is vital that the intended work site is subject to a thorough risk assessment and that the required equipment advised by that assessment are in place before undertaking the task.

Areas to consider include:

PRIMARY AIR SOURCE
This can be a factory airline, a compressor or compressed air cylinders. If a factory airline or compressor is to be used, is the air supply clean? An AFU will only remove water, particulates and oil mist. If there is any possibility of Carbon Monoxide or Carbon Dioxide in the air supply, then an air purifier will need to be used or an alternative clean air supply found.

SUPPLY PRESSURE WARNING DEVICES
How will the wearer know if there is a drop in medium pressure supply?
Inline warning whistles give an audible warning, whereas a DS4 (automatic distress signal unit) provides both audible and visual alarms.

RESERVE AIR SUPPLIES
Do you need to provide an alternative supply of air?
In addition to being standalone supply systems, the Sabre Modulair trolley system can be used as a back-up system, should a compressor supply fail.

CONNECTING UP THE SYSTEM
How are you going to connect the users to their air
supply? Sabre have a range of hose types and lengths and CEN approved couplings to meet your operational requirements.

CHOOSING THE RIGHT AIRLINE BREATHING APPARATUS FOR THE JOB IN HAND
Will the wearer always work from the same airline supply line? Will mobility between lines be required?
Is the wearer working in a confined space? Depending upon the answers to these questions, the Sabre Flite or RAS provide effective solutions to these important considerations.

The Sabre Modulair is a compact, easy to use airline trolley system designed to provide portable clean air in restricted access areas. Versatile and robust, it consists of a lightweight stainless steel hose reel unit and cylinder frame that can be used independently or together. The frame is designed to carry a pair of cylinders and, where required, an additional frame can be vertically stacked to allow connection of up to four cylinders.

This, in conjunction with proven 300 bar high performance pneumatics delivering up to 1000 litres of breathing air per minute, permits four people to work at the same time. Long duration operation is made simple through adjustable cylinder bands and high pressure cylinder connectors to accommodate a variety of cylinder sizes at both 200 and 300 bar. Non-return bleed valves fitted to the cylinder connectors enable cylinders to be replaced independently for continuous operation.

To safeguard against any drop in air supply pressure the Modulair can be fitted with a medium pressure warning whistle or a DS4 (automatic distress signal unit) for both audible and visual alarms if the airline supply pressure falls below 3.8-4.1 bar (55-60 psi). In either case, the operation of the alarm informs safety rescue personnel to switch over to the reserve air supply, change cylinders or initiate evacuation procedures as appropriate.
