Polaris Genuine OEM 3900 All-Purpose Dual-Chamber Zippered SuperBag

The Polaris 39-310 SuperBag is the large, double chambered debris bag for the 3900 Sport and P39 pressure side cleaners, and it also fits the 280, 280 Tank Trax, 280 Black Max, TR28P and 480.

Capacity

The two chambers expand to hold about 5 liters of leaves, twigs and fine debris, close to twice what a single chamber Polaris bag holds. On a pool that sheds a lot of leaves that means fewer stops to empty the cleaner and less chance of a full bag stalling it mid cycle.

Emptying

Each chamber has its own zipper. Unzip both wings, shake the contents out and hose the bag off. The gray fabric shows when it needs a rinse.

Genuine part

This is the Polaris factory bag, part 39-310, not an aftermarket copy.
