Aerial Firefighting - When fighting fires with our S61-A we utilize our Isolair 4600-S61 Eliminator II tank or our Fast Water Bucket System.

Our Isolair Eliminator II tank holds 1,000 gallons of water and has a 100 gallon foam capacity.  It is capable of being loaded with retardant over the wing.  The hover pump allows the tank to be filled in 60 seconds. Your load volume, dump volume and drop length are all precisely controlled by the pilot.  Therefore it is ideal for variable filling abilities and split drops which increase production while reducing costs. This reduces the price per gallon of water dropped as you can adjust your water intake to your fuel burn off and therefore increase your water load accordingly.  Since the tank is fixed to the aircraft it is not considered an external load and is therefore very beneficial in urban or congested areas.

Our Fast Bucket System is utilized with an external long line for dip sites that are inaccessible by tank equipped aircraft.  This unit also has variable fill capabilities therefore decreasing the price per gallon of water dropped.
