Operating at a whisper-quiet 38 dB and consuming just 45W, it features a unique self-adjusting piston stroke to protect against pressure spikes and overheating. Its oil-less, low-maintenance design combined with a self-cooling system ensures a reliable 6-year lifespan, making it a top choice for professionals seeking durable, efficient air pumps. ## Description Ideal for liquid mixing(i.e., bubbling) and smaller aquaculture applications, Medo LA-45C is a low noise, energy-efficient, easy-to maintain aerator that needs no lubrication SPECIFICATIONS Model LA-45C Power Supply AC 120V. Rated Frequency 60Hz. Operating Pressure Range 0.71 - 2.13 psig. Rated Pressure 0.11kgf/cm2(1.56 psig). Rated Airflow* 45 LPM (1.59 cfm) or over. Power Consumption 45 W @ 60 Hz. Running Current 1.0 amps. Operating Noise 38 dB Max. Weight 3.0 kg. Highly reliable, unique, die cast piston construction. UL-approved for outdoor use. Integrated grounded line cord. Service life expectancy of 6 years with proper installation and periodic maintenance. Environmentally conscious design allows the pump to operate with lower energy consumption as it requres only 50-60% of the line currrent typically used by diaphragm pumps. UL-listed for outdoor use Low Noise Level The pumps operate at a very low noise level, about that of a light ballast, as there are no crankshafts, connecting rods or ball bearings to create additional noise. Low power consumption With the piston as the only moving part, frictional losses are diminished which allows for lower starting and running current. Line current requirements are only 50-60% of that typically used by diaphragm pumps. Automatic Pressure Adjustment Designed to self-adjust should the pressure exceed the rated value of the pump, the piston stroke will automatically shorten to reduce the strain on the pump. At the same time, power consumption of the pump will decrease to protect against possible increasing Self-cooling design Air drawn in through the intake valve over the coils reduces the temperature seen in the interior of the pump. MEDO pumps feature a unique, patent-awarded linear-motor-driven free piston system that is globally proven in the wastewater treatment and aquaculture industries. ## Features - Life expectancy of 6 years can be seen with proper installation and maintenance of the pump - Quiet operation allows the pump to run without disturbing the homeowner as can be the case with rotary vane units. - Designed to self-adjust when the pressure exceeds the rated value of the pump, the piston stroke will automatically shorten to reduce the strain on the pump. At the same time, power consumption of the pump will decrease to protect against possible increasing temperatures. This is a definite advantage as diffusers can start to become clogged without the homeowner being aware of it. - Self-cooling design draws cooler intake air over the coils reducing the temperature seen on the interior of the pump extending the life of the unit. - Easy maintenanceProviding maintenance on the pump is relatively easy with a completely oil-less design and no need for additional lubrication. Along with changing the filter as required, the only component to replace in the pump afte an extensive operating period is the piston. ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B01J24ARVG | | Batteries Included? | No | | Batteries Required? | No | | Best Sellers Rank | #285,462 in Industrial & Scientific ( See Top 100 in Industrial & Scientific ) #5 in Piston Pumps | | Customer Reviews | 4.9 4.9 out of 5 stars (30) | | Date First Available | July 25, 2016 | | Is Discontinued By Manufacturer | No | | Item Package Quantity | 1 | | Item Weight | 7.7 pounds | | Manufacturer | Medo | | Part Number | MedoLA45 | | Power Source | Corded Electric | | Product Dimensions | 8.2 x 7.2 x 8.1 inches | ## Images ![Medo LA-45 Piston Air Pump - Image 1](https://m.media-amazon.com/images/I/413oTvlpU6L.jpg) ## Frequently Bought Together - Medo LA-45 Piston Air Pump - AQUANEAT Aquarium 1 Way Thread Valves, Air Flow Control Valves, Manifolds Distributor for Pumps Fish Room Air Systems,20pcs --- ## 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.jp/products/33151111-medo-la-45-piston-air-pump](https://www.desertcart.jp/products/33151111-medo-la-45-piston-air-pump) --- *Product available on Desertcart Japan* *Store origin: JP* *Last updated: 2026-06-26*
