Gas gun is a relatively mature bird repellent product, which is widely used at home and abroad. By detonating LPG, the liquefied gas is mixed with air and then exploded, causing a great noise to frighten nearby birds and fly away. The gas gun developed by our company has two forms: fixed and vehicular, which can be operated by wireless remote control. The gas gun is equipped with a wireless receiver. The gas cannon can be controlled by remote control by the general control system, and the timing device can be used to open the gun automatically according to the predetermined time.
