Refilling – Refilling the HEED 3 is simple and fast. The always on design will deliver “air when you need it”

HEED 3 - Refilling

Refilling is easy from any filled 3000 psi SCUBA Tank.

Step One: Attach the Yoke Adapter to the Check Valve of the HEED 3 Unit. Be sure Yoke is snug against the O-ring on Check Valve.

Step 2: Attach the assembled Yoke Adapter and HEED 3 to a filled 3000 psi SCUBA Tank. Be sure the Bleed Screw is tight or closed.

Step 3: Slowly open the valve on the SCUBA Tank to allow air to fill the HEED 3 through the one-way check valve. When filled, close SCUBA Tank Valve.

Step 4: To remove the Yoke from the SCUBA Tank, release the pressure in the Yoke Adapter by loosening the Bleed Screw. Tighten again after pressure is released to prevent loss of the Bleed Screw.

Step 2 - Attach Yoke & HEED 3 to SCUBA Tank

Step 3 - Slowly open valve on SCUBA Tank

Step 4 - Open Bleed Screw to release pressure

The HEED 3 is a refillable fully self contained breathing device. Refilling is about as difficult as refilling a bike tire. Simply attach the patented refill adapter to any breathing air compressor or filled standard size 3000 psi SCUBA tank. The always-on regulator is ready to deliver life-saving air in an underwater emergency or toxic air environment.

The included Dial Gauge displays an accurate pressure reading in increments of 200 psi. Store the HEED 3 at full pressure and refill it only if you use it. That way it is always ready when you need it.

Note: if the unit is completely emptied of air in any underwater conditions, refer to the manual regarding proper servicing before refilling your HEED 3.

The HEED 3 is designed to be filled quicly and easily from any breathing Air Comporessor

The HEED 3 regulator refills quickly and easily using any breathing air compressor (shown here with the compressor adapter attached to the check valve).

Optional Air Compressor for easy refilling

Available in Gas or Electric Models, the Nuvair 3.5G Compact Portable Air Compressor (part #3100-COM) is an extremely reliable compressor ideal for filling cylinders quickly, usually in less than 30 seconds per cylinder. The compact dimensions and light weight allow for easy transportation and safety.
