When you're shopping in compressors blowers air treatment, the biggest decision tension is usually reliability versus upfront cost. A used industrial air compressor can save a shop thousands, but only if the drive package and pump are sound. The Gardner Denver EDE99M 50HP Air Compressor (2000) New motor tries to solve that by pairing a used base unit with a brand-new Baldor motor installed in October 2025.
Quick Verdict
This is a stationary, horizontally oriented rotary screw compressor rated at 50 horsepower and powered by electricity. The listing describes it as being in good working order and ready to be installed and used in an industrial setting. The standout feature is the newly installed Baldor motor, which directly addresses the most common failure point on an older compressor. At USD 5,000, you're paying for a functional 50 HP industrial air supply package rather than a new-unit price.
Who It Suits
A 50 HP rotary screw compressor is aimed at shops with real compressed air demand-think manufacturing floors, fabrication shops, or facilities running multiple air tools or production equipment. Because the unit is stationary and horizontal, it's best suited for a permanent installation spot rather than a mobile or temporary setup. If you have the floor space and need a mid-to-large electric compressor, this Gardner Denver fits the profile.
What Stands Out From the Listed Details
The most notable detail is the new Baldor motor, which was installed in October 2025 according to the description. That gives the buyer a fresh drive component on a used machine. The unit is also described as being ready to be installed, meaning it's not a project unit requiring reassembly before use. The rotary screw design is a match for continuous-duty applications, and the 50 HP rating gives it serious output capability.
Another point in its favor is the condition note: the listing says the air compressor is in good working order. While that doesn't replace an in-person inspection, it does suggest the seller is presenting the unit as operational rather than as-is for parts.
Meaningful Trade-Offs
The trade-off is the age of the base compressor. The title includes (2000), so this is not a new machine. Even with a new motor, the rest of the compressor-such as the airend, cooling system, and controls-remains from the original unit. Buyers should be prepared to evaluate those components before installation. Additionally, this is a used industrial purchase, so you're accepting that there may be normal wear consistent with the machine's age.
Another consideration is the price point. At USD 5,000, this sits in a range where you could also explore other used 50 HP options, but the newly installed motor is a concrete reason to consider this particular listing.
Gardner Denver EDE99M 50HP Air Compressor (2000) New motor
If you're specifically looking for a 50 HP stationary rotary screw compressor and want to avoid the risk of an old motor, this unit makes a strong case. The new Baldor motor is the kind of upgrade that can extend the useful life of an industrial compressor. The limitation is that the rest of the machine is still a 2000-era unit, so you'll want to inspect the overall condition and listen to it run if possible. For a shop that needs 50 HP of continuous compressed air and can handle the used-equipment variables, the listed USD 5,000 price is a concrete figure to weigh against the new-motor advantage.
Bottom Line
The Gardner Denver EDE99M 50HP Air Compressor (2000) New motor is best for buyers who want a mid-sized industrial rotary screw compressor with a major component already replaced. The combination of the Gardner Denver name, the 50 HP electric rotary screw setup, and the fresh Baldor motor makes it a serious candidate. Just keep in mind that the base machine is from 2000, so the overall condition of the non-motor components deserves attention before you commit.
