General Information
You have purchased a Respirex Simplair air supplied blouse. This equipment is for use within certain
contaminated environments only. You must carefully read and follow these operating instructions closely.
The Respirex Simplair range of protective clothing is designed for use with breath- able air supplied
from an external compressed air source providing positive pressure. The air owing into the garment
must conform to EN 12021 Annex A.
Respirex Simplair Blouses are supplied in a range of sizes, styles and materials. All Respiratory
Protective Clothing is CE marked to indicate compliance with the European personal protective
equipment (PPE) Regulation (EU) 2016/425. Respirex Simplair Blouses have been tested to meet the
requirements of the European standard EN 14594 for respiratory protective devices and EN 14605
for protective clothing providing protection to parts of the body against liquid chemicals. For further
information on the performance results of each specic material refer to the data sheet supplied with
the hood.
Limitations & Warnings
When worn alone a Simplair air supplied blouse provides only partial body protection.
If full body protection is required a blouse worn in conjunction with chemical protective trousers, gloves
and safety boots will meet the performance requirements for ventilated and non-ventilated “non-gas-
tight” (TYPE 2) protective clothing.
At high work rates the pressure in the garment may become negative at peak inhalation ow or during
bending or squatting.
Adequate protection may not be provided by the garment in atmospheres that are immediately
dangerous to life or health.
The garment must NOT be used with oxygen only or oxygen enriched air.
Care must be taken to ensure that the garment is being used from the correct length and bore of air
supply hose, as a low airow may cause a less ecient protection.
The equipment is designed to work on a range of airline pressures. The blouse is preset by Respirex to
operate at the customer’s specic air line pressure (the maximum air line pressure that the blouse can
be set to is 120 PSI.
Unless otherwise stated by Respirex the material fabric of the garment does not breathe. Your body
temperature will rise when working in the garment therefore you are advised to leave the work area in
the event you feel too much body uid has been lost.
The garment must only be used in the hazardous area for which it is intended. Always follow the
instructions carefully otherwise the protection oered by the garment may be drastically aected.
Always use compatible PPE, e.g. chemical protective trousers, jackets, gloves and safety boots
advised by Respirex.
For any inquiries please contact the Respirex customer services department on Tel:
[phone], Fax: [phone] or E-mail: [e-mail].
Pre-checking the Air Supplied Blouse
Under the Control of Substances Hazardous to Health (COSHH) regulations 2002 and the Personal
Protective Equipment at Work Regulations 1992, a thorough examination of respiratory protection
equipment (RPE) is required to be under taken in a clean area at least once per month if the garment
has not been used. When in use Respirex recommend that the RPE is always checked before the start
of each shift cycle. These inspections are required to ensure that the RPE will perform as intended and
is free from defects.

4
Each inspection must be recorded and the following noted date, serial number, name of examiner,
condition of the equipment and details of any defect found. Relevant Health & Safety departments for a
period of at least ve years will keep the inspection records.
1. Visually inspect the blouse for any damage that may impair the correct working of the garment
together with the gloves.
2. Check that the gloves are correctly tted (see page 6).
3. Check correct airow in the blouse. The blouse will be marked with its working pressure that
must correspond to the factory airline pressure as indicated by the pressure gauge at your airline
supply outlet point. Ensure that the silencer is clean and free of any contamination from the airline.
The silencer must be re- placed if it is contaminated to any extent.
4. The blouse is free from contamination both inside and out.
5. The identication number is clearly legible in the blouse.
6. The blouse materials are free from tears and holes, including the head of the garment. Pay
particular attention to the seam areas.
7. Ensure that the waist belt air attachment is secure and not damaged.
8. A clean silencer is tted.
9. The vision from the visor is not obstructed by large scratches and heavy scu marks. On blouses
tted with rigid visors a removable outer visor can be tted which prevents damage to the main
visor. This can be changed by simply peeling away from the Velcro fasteners and replaced with a
new outer visor.
10. Respirex recommend that the exhalation valves are part of the visual pre-check. If the valve
diaphragm is distorted or damaged in any way it must be replaced (see page 11).
Inspection of the compressed air supply tube (medium pressure connecting hose) which supplies
breathing quality air to the operator must be carried out at least once per month and before each shift
cycle and the results recorded.
During the inspection the following should be checked:
1. Lines are clean externally.
2. Lines are free from damage (holes, splits, etc).
3. Airline coupling connections are in good condition and the non-return valves are in good working
order.
Submerge in water to locate any leaks if any sign of external damage is evident.
Report any defects to the supervisor and record them. The compressed air supply tube must NOT be
used until the defect has been rectied.
Maximum Length And Bore Of Medium Pressure Connecting Hose
Respirex recommend a minimum of 3/8” internal diameter bore hose is used approved to EN 14594.
If other Medium Pressure Hose and couplings are to be used they should be suitable for the intended
use and conform to the requirements of EN 14594 (a sample must be supplied to Respirex to enable
the correct air settings to be achieved).
The garment will be set by Respirex to give the correct rate of airow to coincide with the customer’s
supplied airline pressure, as notied to Respirex and indicated on the airline waist belt label. The
user shall assure himself that the pressure range of the air supply to the apparatus is within the limits
recommended by Respirex.
Maximum And Minimum Flow In Litres/minute The airow to the blouse must be within the range:
Maximum 340 L/Min
Minimum 270 L/Min
This must be checked prior to each use by means of the Respirex airow meter. (See page 5).

Checking The Air Flow In The Blouse
Fig.1
1. Lay open the blouse to allow access to the air system.
2. Unscrew the connecting collar from the bulkhead adaptor.
3. With the Respirex ow meter on at a level surface; screw the tube connector from the ow meter
onto the bulkhead adaptor.
4. Connect the garment onto the air supply and measure the airow on the meter. See page 3 for
correct ow rates.
5. Disconnect the ow meter and reconnect the air system.
Should you be unable to achieve the airows indicated, then the silencer should be replaced.
Note: Respirex recommend customers set up their own silencer replacement programme. The quality
of the air and the frequency of use of the garment will determine this.
Minimum Flow Warning Device
1. With the Respirex ow meter connected to the air system turn the air pressure down to obtain the
minimum airow into the garment.
2. When the minimum airow is reached the warning device will sound a high pitch whistle.
3. After checking the minimum ow warning device, set the air pressure back to the correct working
pressure.
