The BelAire 4918VN is a compact 5 HP, 230V single-phase air compressor designed for home garages and smaller workshops that need serious airflow without giving up much floor space. Its vertical design measures 36" L × 24" W × 73" H and delivers 16.1 CFM at 100 PSI. The pump uses solid cast iron construction and stainless steel valves, a combination aimed at long-term durability in the components that handle repeated heat and motion. At 382 lbs, this is still a permanently installed machine rather than something you move around the shop. Note: published information conflicts on the tank size, pump staging, and electrical requirements, so confirm those details with us before ordering if they affect your installation.
The stainless steel valves are one of this compressor's most important details. Compressor valves repeatedly open and close in hot, oil-containing compressed air, making them a significant wear point over the life of the pump. The belt-driven, splash-lubricated design allows the pump to operate at a lower speed than the motor, while an oil sight glass makes routine oil checks straightforward. A fully enclosed high-flow belt guard protects the moving drive components, and start-stop pressure switch control shuts the motor off once the receiver reaches its cut-out pressure. Each unit is also 100% factory tested at full pressure before leaving the plant.
The 4918VN is a practical choice for home and hobby garages, small workshops, and dedicated workstations running impact tools, ratchets, and blow-off equipment. Its narrow vertical footprint also makes it useful as a secondary compressor or backup air supply in a larger operation. There is no air dryer or aftercooler, so moisture management should be part of the installation—especially for paint or other applications that require cleaner, drier air. This model is best suited to intermittent-duty use rather than continuous production air.

Certification, Stated Honestly
The manufacturer describes the tank and safety valves as ASME/CRN certified. This is pressure-vessel certification for the receiver.
Our data records no third-party safety listing for the complete compressor, so we will not imply one. If your insurer or site requirements call for a specific listing, tell us which one and we will confirm in writing whether this unit carries it before ordering.
Shipping & Delivery
Ships by palletized freight to the lower 48 states. You will need a loading dock, forklift or suitable unloading plan; at roughly 600 lbs, this is not a two-person lift. Terminal pickup is an alternative if your site cannot receive the pallet safely. Residential delivery carries an additional fee.
Inspect before signing. Check the crate and compressor with the driver present. Record any damage on the bill of lading and photograph the pallet before breaking it down.
Warranty
The listing states a 2-Year Full Warranty covering the complete machine, including the valves, with no additional purchase required.
If a failure occurs, stop using the compressor and contact us before disassembly. Keep the pump, motor and pressure switch intact for inspection, photograph the condition as found, and follow the manufacturer's claim process.
