Ningbo Aier Ventilation Equipment Co., Ltd has recently launched another type of its access door series for the ventilation ducts – Flat Access Door.
What is Flat Access Door?
Flat Access Doors are designed to provide inexpensive and trouble free access to the rectangular air ducts for ducts cleaning and maintenance. The flat access doors are made out of hot-dipped spangle-free galvanized steel (Dx51D+Z275) with polyurethane as the gasket.
Advantages of Flat Access Door?
Our flat access doors are anti-corrosion and rust-proof – zinc coated Z275 (16-22 µm);
Our innovative handle design allows our flat access doors to be pushed and pulled instead of managed by twisting a knob when installed on the duct. This makes handling the access doors much easier.

How Our Casting Aluminum External Louvre Achieved High Quality
How to compete with other suppliers on the market? Answer: differentiation!
Are low prices the most important advantages? Not really.
Differentiation allows us to provide our customers with a superior value at affordable prices, thus creating a win-win situation that can boost the overall profitability and viability of your business.
Take Our Casting Aluminum External Louvre as an example.
A Story About the Casting Aluminum External Louvre
Some time ago, a potential customer was inquiring about our casting aluminum external louvre. He has acquired several offers from other suppliers too, but in the end opted out for a lower priced solution with another supplier. The very same customer came back a few months later and told us that the supplier he had chosen before provided bad quality. Coincidentally, we have decided to do a little research of the market’s supply at that time. Testing and examining several casting aluminum external louvres made [...]
At Ningbo Aier Ventilation Equipment, we continuously work on developing and providing more comprehensive services to our customers in order to fully meet every need they might have. In such spirit, we have also developed plastic air valves and stainless steel air valves to satisfy customers’ diversified specifications.
What are Plastic /Stainless Steel Exhaust and Supply Air Valves?
Both Plastic Air Valves (PAV) and Stainless Steel Valves (SSAV) have the same functions as the metal ones. They are designed to offer simple but effective means of providing air supply and air extract for most commercial, industrial and domestic ventilation applications. The only differences in contrast to metal valves are materials used and their construction. The plastic air valves and the stainless steel air valves can be used for both air supply and air exhaust (2 in [...]
Air valves are designed to offer simple but effective means of providing air supply and extract capabilities for most commercial, industrial and domestic ventilation applications. They are typically installed in hotels, houses, apartments, halls of residence and hospitals and are being used to handle air volumes in small confined and closed up indoor spaces such as toilets, washrooms, utility rooms, or any other small rooms.
What Are The Metal Exhaust and Supply Air Valves Made Of?
The body of an exhaust air valve is made of SPCC steel with thickness of 0.6mm or 0.8mm upon request.
The mounting ring of an exhaust air valve is made of DX53D+Z80 hot dipped galvanized steel (plated zinc thickness 6-8mm)
The exhaust air valve body has a gasket made of circular [...]

IRIS Damper is an ideal air flow regulator and measuring device for the circular ducts. The diaphragm valve ensures a perfect accordance between the diameter indication on the handle and the opening of the valve.
