Product Details

SAFE-X 1000 is a resettable flashback arrestor manufactured in accordance with BS-EN 730.

The model incorporates several unique features. It is designed to be user-friendly, with clear indications of open and closed operating modes. A green stripe indicates in-operation mode. The flashback arrestor closes during flashback, cutting off gas flow. The design includes a reset mechanism.

With the system decompressed and the cause of the flashback determined, the SAFE-X 2000 is reset by pulling the reset button out until the green stripe appears again.

SAFE-X 2000, of course, has all the safety functions you can demand from a modern flash back arrestor.

- A filter which prevents contamination affecting the function of the flashback arrestor.

- Flame arrestor of sintered metal, which stops and extinguishes backfire.

- Non-return valve which prevents flow-back.

- A flow-arrestor which automatically turns off the gas flow on flashback.

- Safety fuse which shuts off the gas flow on overheating.

Flashback Arrestors FAQs

Straight answers to the questions people ask most when choosing, fitting and looking after flashback arrestors.

What is inside a flashback arrestor and how does it stop a flashback?

Most arrestors combine several safety devices in one body. A non-return valve stops gas flowing backwards, a flame arrestor (a sintered or metal element) absorbs the heat and stops the flame travelling on, and many also have a cut-off valve that shuts the gas flow when a flashback is detected by pressure or temperature.

The exact design varies by maker and by gas. This is why an arrestor must be the right type for the gas it is used on, and why it should never be taken apart or modified.

What is the difference between resettable and non-resettable arrestors?

After a flashback, a resettable arrestor can be put back into service by following the maker's reset procedure, usually once the cause has been found and the unit has been checked. A non-resettable arrestor has done its job once and must be replaced.

Resettable types are convenient and are common on modern equipment, but they still need to be tested and inspected as the maker directs. If an arrestor has stopped a flashback, treat the rest of the hose and equipment with suspicion and have it all checked before using it again.

Does a flashback arrestor restrict the gas flow?

Every arrestor has some resistance to flow, because the gas has to pass through the flame arrestor element. For normal welding, cutting and heating this makes no noticeable difference. For high-flow work, such as large heating nozzles, you need an arrestor rated for the flow you are using.

Check the maker's flow rating against the nozzle you plan to use. If the flame seems starved or weak and the regulator is set correctly, a blocked or undersized arrestor is one possible cause worth checking.

How often should flashback arrestors be tested and replaced?

There is no single interval that suits every arrestor. The maker's instructions for your own unit give the test method, how often to check it, and any maximum service life, so read them and check the markings or date on the body.

In general, arrestors should be inspected regularly, with a check of the non-return valve and a leak check on the connections. Check more often if the equipment is used hard, in dirty conditions or has been involved in a flashback. Many workshops include them in a routine inspection of all gas equipment and keep a record.

If an arrestor fails a check, is damaged, or has passed its service life, take it out of use and replace it. Your risk assessment will say what is required for your work.
