The B310 is made to sit in your cargo area or onto a seat in your aircraft, either connected to a drain to the outside of your aircraft or strapped onto the B310’s fitted drain basin. The unit is securely strapped into place against a bulkhead using the handles built onto the unit. Up to four feather-weight hoses are sent forward into the cabin to the seats you choose; the cigarette lighter adapter is brought forward to the cigarette lighter where it is plugged, ready for use at the flip of its LED rocker-switch.
Each hose ends in Pol-Air’s patented ‘seat-slide’ and is the breakthrough that makes true microenvironmental cooling possible. When not in use, each seat-slide lies on the floor of the aircraft attached to its hose. When the user is ready, the tongue of the slide is placed beneath a thigh or the crotch so as to position the nozzle of the hose to blow cool air onto the user’s face, neck, chest, and abdomen. This directs the cooling to the body’s core where it is needed first and not the entire cabin. If you decide you do not want the ‘seat-slide’, permanently remove it and place the tubes directly under the shirt or wherever cooling is needed.
Any hose not in use may be capped off by the use of a simple 1-inch PVC pipe cap (unthreaded). These are provided. This will direct the 14.3 CFM (cubic feet per minute) air-flow (in the 12vDC models) into the remaining nozzles for extra cooling of the other passengers. The entire output of the B310 can blow out through one hose or any combination up to four hoses as desired. Thus you can quickly tailor the ‘seat slides’ for whatever combination of passengers you may be carrying on your next flight.
The B310 can provide 75 to 90 minutes of cooling on one 25 pound load of rough crushed ice. The fine/peanut crushed ice will fit 35 pounds of ice into the cooler and will last considerably longer. It provides immediate cooling for you as your get into your cockpit, while you do your checklist, warm-up, tower contact and clearance, taxi, take-off and climb to altitude. Once at cool air altitude, you can open your vents and shut off the B310 using the rocker-switch in your cigarette lighter.
Once you begin to descend into warm air, you simply cut off your vents, switch the B310 back on and keep yourself cool through descent, landing, and taxi to your final destination without breaking a sweat!
If you have connected the B310 directly to an outside drain, any water from melting ice will have drained out immediately. If you are unable to drain out directly and have used the water drain basin, you use the supplied hand bulb to siphon all remaining water from the basin upon arrival at destination. This is done by hanging the hand bulb out the cabin door below the level of the basin and pumping it a couple of times until the flow of water starts. This will then siphon the entire basin dry and leave no water in the aircraft to later vaporize and corrode avionics contacts. This hand bulb can also be used to bulb a cup of ice water from the basin in flight.
Refilling the B310 unit is easy. Just pop the lid off the insulated case strapped down in cargo and drop in your ice. Seal the lid back onto the case and you are ready to fly cool and dry. Do remember to strap the lid to the case in case of turbulent air.
