An anti-vibration base for air conditioner outdoor units. The top pad uses high-performance damping material to absorb compressor and fan vibration before it reaches the structure, which is what stops the low-frequency hum travelling into walls and floors. The base is rated to 300 kg and suits most domestic condenser units.
In ceiling voids, service risers, floor build-ups and wall chases, ducting is rarely the whole system — it is one link in a chain. Getting it wrong shows up later as condensation, pressure loss, noise transmission and awkward routing. The selection criteria that actually drive performance are air-tightness, pressure drop and acoustic performance, and those are the three things a buyer should confirm before placing an order.
Pressure loss in a duct run does not scale linearly with diameter — it scales roughly with the inverse fifth power of it. That single relationship explains why stepping a run down by one nominal size to save ceiling depth so often destroys the performance of the whole system. A modest reduction in diameter can multiply the resistance of that section several times over, and the fan then has to run faster to compensate, which raises both energy consumption and noise. When a void is tight, the correct answer is almost always to re-route rather than to reduce the diameter.
Warm moist air passing through a duct that is colder than its dew point will deposit water somewhere along the run. In practice the deposit forms at the coldest point, which is normally a joint, a bracket or a section that passes through an unconditioned loft or a wall chase. The damage is progressive and largely invisible: staining appears on a ceiling months after the actual defect occurred, by which time the insulation and often the substrate behind it are already affected. Continuous, unbroken insulation across every joint is the only reliable defence, and it costs nothing at installation time.
Every Anti Vibration Base for Air Conditioner Outdoor Unit, Shock Absorbing AC Condenser Support Bracket with 300kg Load Capacity for Household Commercial HVAC Systems we ship is produced on our own production line in Dezhou, Shandong, China. Because we control the tooling and the forming equipment directly, we can guarantee that the product you receive in container three is dimensionally identical to the sample you approved in the first order. That consistency is difficult to achieve when production is outsourced, and it is the single most common complaint we hear from buyers who have tried sourcing this category through intermediaries.
Our mould shop supports custom development for Anti Vibration Base for Air Conditioner Outdoor Unit, Shock Absorbing AC Condenser Support Bracket with 300kg Load Capacity for Household Commercial HVAC Systems. If your project needs a non-standard size, a specific wall thickness, a particular colour or a branded face plate, we can build the tooling and run a trial batch for approval before committing to a full production run. Typical custom development takes two to four weeks from drawing approval to first article, depending on the complexity of the part.
Confirm the exact size or model you need against the specification table below. Where a project mixes sizes on one run, check that every transition is made with a matching reducer rather than by forcing parts together — the latter is the single most common cause of leakage and pressure loss on site.
The material and layer build-up determine how the product behaves over a 15–25 year service life. Read the construction column carefully: two products that look identical on a photograph can differ entirely in wall thickness, insulation layer and fire performance.
