It runs smoothly and is quieter than the original motor! ### ⭐⭐⭐⭐ GREAT *by H***. on April 11, 2025* GREAT! NO INSTRUCTIONS INCLUDED THOUGH ### ⭐⭐⭐⭐⭐ Motor works great ! Amazon delivery was NOT !!! *by B***E on May 4, 2025* The motor so far is running great and was an exact bolt on replacement for the air compressor. Amazon as usual FAILED TO DELIVER in the time it advertised, and my shop was down due to waiting on a motor that was promised in two days and took 5 to deliver. Amazon delivery continues to FAIL, Prime use to mean something, now it is just a video service. ## Frequently Bought Together - NEW 3.7HP COMPRESSOR DUTY ELECTRIC MOTOR, 56 FRAME, 3450 RPM, 5/8" SHAFT DIAMETER, NEMA RATED MOTOR, REPLACES 5HP SPL MOTORS RATED 15-17AMPS - BlueNatHxRPR 64-77 MFD/uF Motor Start Capacitor Withstand Voltage 250V AC - ZH-B 250V-400V 16(8) A Industrial ON-Off-ON Universal Switches Change-Over Switch Permutator for Controlling Motor Reverse Direction --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.ie/products/73044764-new-3-7hp-compressor-duty-electric-motor-56-frame-3450](https://www.desertcart.ie/products/73044764-new-3-7hp-compressor-duty-electric-motor-56-frame-3450) --- *Product available on Desertcart Ireland* *Store origin: IE* *Last updated: 2026-05-23*
