1. An air assembly for use with an inflatable product, the air assembly comprising:
a main body forming a main body chamber, the main body comprising at least one vent in communication with the inflatable product;
a control panel coupled to the main body and accessible from an exterior of the inflatable product, the control panel comprising a vent in communication with the surrounding environment and the main body chamber;
an actuator disposed on the control panel;
a transmission member actuatable by the actuator and extending into the main body chamber;
a pump body disposed in the main body chamber;
a pump cover disposed in the main body chamber, the pump cover cooperating with the pump body to form an impeller chamber and including an air inlet and an air outlet in communication with the impeller chamber;
an impeller disposed within the impeller chamber;
a motor disposed within the main body chamber and operably coupled to the impeller, the impeller configured to direct air from the air inlet to the air outlet of the pump cover; and
a directional control valve coupled to the transmission member and disposed within the main body chamber, the directional control valve moveable between:
a first position corresponding to an inflation state in which the directional control valve opens an airway between the air outlet of the pump cover and the at least one vent in the main body to inflate the inflatable product;
a second position corresponding to a deflation state in which the directional control valve opens an airway between the air inlet of the pump cover and the at least one vent in the main body to deflate the inflatable product; and
a third position corresponding to a closed state in which the directional control valve blocks airflow between the pump cover and the at least one vent in the main body to close the inflatable product.
