Cleaning solution for bus or subway vehicle air duct
Bus air conditioning mode is generally through the vehicle two side of the duct to the interior of the car from the air conditioner in the top of the vehicle, by each outlet pipe of the cold air spread to every corner of the carriage, return the return air inlet is located in the middle or the rear vehicle (pipeline) returned to the air conditioning unit.
Because the vehicle the space is relatively small, so the wind pipe section sizes are small and are mostly flat and corners are right angle, so the vehicle air duct cleaning usually building air duct cleaning robot will not be able to use common, because the air duct cleaning robot relative volume more suitable for building large cross section the wind pipe.
According to the experience of bus air conditioning cleaning the selection of various types of models for many years “Brontosaurus” flexible machine (Tornado) equipment or air knife cleaning equipment is the most effective tool, truly effective cleaning the bus duct, there are a number of advantages.
(1) all types of “Brontosaurus” flexible machine (Tornado) equipment or air knife cleaning equipment has the advantages of small volume, can be smoothly into the wind pipe internal cleaning section 100mm*100mm or 50mm diameter.
(2) all types of “Brontosaurus” flexible machine (Tornado) equipment or air knife cleaning equipment due to its rotating shaft or the wind  onveying pipe is very soft, can be freely bent pipe, can be very smoothly through the right angle bend.
(3) because of the interior of the vehicle is narrow, a common “dust cleaning method” no enough space to display, and “Brontosaurus” flexible machine (Tornado) equipment or air knife cleaning device equipped with tornado device uses a “direct suction method” can effectively solve this problem.
(4) all types of “Brontosaurus” flexible machine (Tornado) equipment or air knife cleaning equipment with high efficiency without the wind pipe is provided any process hole, no damage to the wind pipe.
