The Castair VP1575 is a set of four small round rubber vibration pads, each measuring 1.5" diameter x 3/4" thick. At $4.62 for the set, these are the smallest vibration isolation pads in the Castair lineup — intended for smaller compressors, small motor mounts, and equipment with compact feet that won't accept a 4" x 4" pad. If you're mounting a fractional HP compressor, a small air dryer, or any equipment with small-diameter mounting feet, these round pads provide the same vibration isolation function as larger pads but sized to fit the application.
Round vs. Square Pads — Selecting the Right Size
Round vibration pads are used when the equipment has circular or small-diameter mounting feet. Most shop compressors in the 3 HP and above range use square or rectangular foot pads (the 4"x4" VP100/VP1004 series). Smaller compressors — particularly portable units, small pancake compressors, or equipment with bolt-through mounting feet rather than flat-bottomed contact feet — use smaller pads. The 1.5" diameter fits bolt-through installations where the pad mounts around a bolt or in a small-diameter counterbore.
Key Features
- Dimensions: 1.5" diameter x 3/4" thick, round — sized for small-foot equipment and bolt-through mounting applications
- Set of 4: Covers all four mounting points on standard equipment
- Rubber Construction: Anti-vibration rubber at appropriate durometer for smaller equipment weight loads
- Vibration Damping: Reduces vibration transmission from small compressors and motors to mounting surfaces
- Non-Slip: Keeps equipment from walking or shifting during operation
- OEM Castair Part: Factory-specified for Castair equipment requiring this pad size
Typical Applications
- Small piston compressors with compact foot dimensions
- Small motors or equipment on shelving or benchtop mounting surfaces
- Bolt-through mounting configurations where the pad centers on the mounting bolt
- Secondary equipment (air dryers, filters, regulators mounted on brackets) where vibration isolation is needed
- Any equipment with 1.5" or smaller mounting foot diameter
Vibration Pad Size Selection Guide
- VP1575 ($4.62) — 1.5" x 3/4" round, set of 4 (this part) — small compressors and small-foot equipment
- VP100 ($9.24) — 4" x 4" x 1" square, individual — standard shop compressors, single pad

- VP1003 — Castair VP1003 — contact us for dimensions
Match the pad to the equipment foot: measure your compressor's foot contact dimension and select accordingly. If the foot is smaller than 1.5" diameter, check with us for alternatives.
