| With the improvement of people's life and
that of people's living condition, it is necessary to keep air clean
in the toiletroom.But at present, there is one big problem that it
is hard to drive waste air out of the toiletroom, which of course
will worsen air in the house and the accidents caused by lack of oxygen
and carbon monoxide poisoning will happen from time to time. The automatic
swinging air interchanger invented by our company is designed on the
basis of the problem. This product has won the national patent, the
numbers of which are ZL01210899.5 and ZL02261752.3 and filled in the
national blank, taking the lead in the same kind of the products in
china. In August 2002, all the indexes met the requirements of Q/YH
J01-2002 after the test by Zhejiang Quality & Technology Supervision
Testing Institute. In September 2002,the item was established and
appraised provincially, in December 2002, it was confirmed as a new
high-tech product of Zhejiang province and in 2003, it was presented
to the state to make an application for a key new product. As the automatic swinging air interchanger is mounted on the ventilating duct on the roof of the house and is exposed to the rain and the sunlight, our company uses special materials including stainless steel bearing .It's unnecessary to maintain for a couple of decades and on the other hand, it has an effext of roof decoration. |
| SIZE DIRECTIONS: |
| At present, there is a data requirement for the ventilation of the bathroom domestically and locally, but no requirement for the size of ventalating duct. Thus there is no consistent size requirement in design. We now have two sizes of the automatic swinging interchanger. Their diameters of the bottom seat are ￠350mm(Model ZHQ-350) for high-rise and ￠200mm(Model ZHQ-200) for less-than-ten-storey building. Our company can also make a modifaication as per the customer's request. Your advice is always welcome and we look forward to your cooperation. |
