SE400AT-2 SEA PAPR Respirator

Please note BEFORE purchasing:

This listing is for unused OUT-OF-BOX equipment.  This means that it has never been used, but may contain cosmetic flaws such as light scratches on the faceshield or other parts due to loose storage. 

As seen in the pictures, there is a small plastic clip on either side of the mouthpiece that is either cracked or broken (pictures are general and not exact item buyer receives).  These clips are protective of the exhalation valves only and do not compromise the safety or integrity of the mask at all.  They can be held in place simply with a small piece of tape.

The sets have also been in storage for a period of time and, as a result, the reliability of the batteries cannot be guaranteed.  The batteries have been charged and appear full, but have only been used to power on and test the equipment.  They have not been tested for duration.  No exchanges or refunds can be given for batteries that are not in new working condition.  The equipment has otherwise been tested as fully functional. 

There are NO FILTERS included in this listing.  The SE400 system uses NATO standard 40mm threaded filters, which is a common size filter, available wherever respirator equipment is sold, both online and retail.  Any manufacturer filter with this size thread will fit the SEA SE400.


This listing includes the following:

Full Face Respirator Mask

SE400 Powered Fan Unit

Air Supply Hose

Battery and Charger

Voice Amplifier

BONUS Items Included:

Backpack Harness and Belt Harness ($160 value)

Retail value of complete set is over $2000!

All the air you need
The SE400 gives you true positive pressure air up to and in excess of 400 litres per minute. Conventional fan-assisted respirators give you a mere 120-180 l/min.

Big savings on filters
The SE400 is not a continuous-flow respirator. Air passes through the filters only as you need it. That's why the SE400 uses 50% less filters on average, compared to other fan-driven respirators.

Know what's happening
With the SE400, you will always know that you are getting the protection you need. Visual and audible alarms alert you to any routine task (such as changing the battery), as well as other events that may require your attention.

Voice transmission is loud and clear. SE400 comes with a microphone in the mask and a powerful external loudspeaker.

Single button operation
Put it on. Breathe. It couldn't be easier.

Wear it the way you want
The SE400 can be worn on a backpack, waist harness or standard belt. Fit the hose over your shoulder or around your side.

The SE400 can be worn inside suits of various materials, ranging from disposable dust suits to fully encapsulated gas suits. All suits can be pressurised by the SE400.

Lots of accessories
Full range of filters
Dust, spray, splash and spark hoods
Spark- and flameproof hose sleeves
Welding visors for full face masks
Backpacks, padded waist belts, harnesses with braces
Clear tear-off visor film for spray work
Spectacle inserts for full masks, including prescription glasses, low-light lenses, sun shades, etc.

Hi-tech operation
Micro-processor driven fan operation
Continuous self-diagnostics
Instant user alerts in case of pressure-drop, motor malfunction, low batteries etc.


Shipping Policy:


Shipping is charged by actual weight with no handling charges added. 


International customers may incur customs fees depending on the destination country.  Please be aware of these charges before purchasing.  Also, please do not ask me to list the equipment as a 'gift' or falsify the value of your order to reduce the cost at customs.  It is a crime to file fraudulent documents!  Thank you.


I try hard to ship orders as quickly as possible and it shows in my feedback.  Orders will be tested, packaged and shipped within two business days.  I also try to answer e-mails as quickly as possible.  I usually check my messages late in the evening to catch those that came in after my 'normal business hours'.  I know that customer service is an important part of any sale.  I leave positive feedback upon payment, when the customer's job is done.  Thank you to the many customers who have taken the time to return the favor.  The kind words are greatly appreciated!
