The primary pump uses a 50uF starter capacitor and the secondary pump uses this 40uF starter capacitor. This one is about a half inch shorter than the OEM one and easily fits inside the capacitor housing on the top of the pump. Review: Capacitance Reading was exactly 40uf - So far so good, I got my HVAC compressor running again. Very easy to install. Hopefully, this capacitor is reliable. ## Features - VEXUNGA 40uF ±6% 370/440/450 VAC CBB65 round run start capacitor replacement for ALL 250 & 300 & 370 & 440 & 450 Volt capacitors. - 40 MFD Capacitor size measures ( 1.97inch / 50mm ) in Diameter x ( 3.35inch / 85mm ) in Height. - Operating temperature: -40℃ to +70℃/-104℉ to +158℉.

The primary pump uses a 50uF starter capacitor and the secondary pump uses this 40uF starter capacitor. This one is about a half inch shorter than the OEM one and easily fits inside the capacitor housing on the top of the pump. ### ⭐⭐⭐⭐⭐ Capacitance Reading was exactly 40uf *by B***T on December 19, 2025* So far so good, I got my HVAC compressor running again. Very easy to install. Hopefully, this capacitor is reliable. ### ⭐⭐⭐⭐⭐ Worked on my Cambel Hausfeld *by J***D on June 12, 2024* Recently I inherited this air compressor from my grandpa. It had been sitting for years and would not start. Not a big deal it just needed a little love and a few parts to get it back into service. Both the start and run capacitors were replaced, this got the motor running, but it wasn't shutting off cleanly (it was just bogging down the motor) so I needed a switch. The old one (manifold with regulator) is no longer made and the replacement uses a switch with 4 ports. You need to add a pressure regulator, safety value, tank pressure gauge and whatever airline fitting you intend on using. It took me awhile to figure out a fix for the original part being discontinued so hopefully this saves someone in the same situation some headache. I'm happy with it. ## Frequently Bought Together - VEXUNGA 40uF 40 MFD 370VAC 440VAC 450VAC 50/60Hz CBB65 CBB65B Run Start Capacitor for AC Unit Fan Motor Start or Pool Pump or Air Condenser Straight Cool - BOJACK 1 Poles FLA 40 Amp Coil 24 VAC Air Conditioner Condenser Compressor Contactor AC Definite Purpose Contactor - BOJACK 35+5uF 35 5 MFD ±6% 370V/440V CBB65 Dual Run Circular Start Capacitor for AC Motor Run or Fan Start or Condenser Straight --- ## 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.vu/products/745963309-vexunga-40uf-40-mfd-370vac-440vac-450vac-50-60hz-cbb65](https://www.desertcart.vu/products/745963309-vexunga-40uf-40-mfd-370vac-440vac-450vac-50-60hz-cbb65) --- *Product available on Desertcart Vanuatu* *Store origin: VU* *Last updated: 2026-05-05*
