Not always. When the unit hangs on a rigid bracket with a bedroom on the other side of that wall, vibration travels through the structure — pads make an audible difference there.
On a separate base or a roof, check first whether there is an actual noise complaint before adding them.
Measure the bolt spacing on the unit feet, then check the unit weight. Matching both is the reliable route.
1–1.5 HP residential units usually take the small single- or double-hole sizes; 3 HP and above, or commercial units, need the thicker high-load models. The A / B / C dimensions in the spec table map directly to the foot spacing.
Size the bracket at twice the unit's total weight or more, and check the wall material.
Solid brick or concrete takes wall brackets; lightweight walls or insulated facades are better served by floor feet that transfer load straight to the slab.
Current ducts are PVC, ivory white as standard, which matches most residential units.
Bulk orders can be produced to a colour card — send quantity and colour code and we confirm MOQ and lead time.
Yes. Send CAD, PDF or a physical sample. We measure and draw, confirm structure and dimensions, then build tooling and samples.
Mass production only starts after the sample is approved, so dimensions stay consistent between batches.
Yes. Standard models ship as 1–2 pieces for test fitting and checking vibration behaviour; sample cost is credited against the order.
Send delivery details and the models you need — dispatch is arranged the same day.
The pad must sit in full contact with the feet and carry load evenly at all four corners. Do not over-tighten the bolts — crushing the rubber removes the isolation.
Keep brackets level and make sure anchor bolts reach the solid substrate; fix duct covers at 1 m intervals or less and close corners with elbows.
Leave your requirement — we reply the same day with model, price and lead time.
