Condition: Like New
Tested, works perfectly, all pieces included, still in original packaging.

The VCRAZE KP-40 Linear Air Pump is a reliable choice for ensuring strong oxygen flow in ponds or aquariums. Its 635GPH output optimizes water quality by delivering powerful and even aeration. This energy-efficient pump uses a 25W copper coil motor, so it runs cool and uses less power. The VCRAZE KP-40 suits koi ponds, aquariums, fish farms, and hydroponic systems, keeping aquatic life healthy and active.

This air pump is designed for quiet running. Rubber and silicone buffers absorb vibration. Its sealed air chamber further reduces noise. A magnetic-driven diaphragm powers the strong airflow. These features allow the KP-40 to operate almost silently, which is great for peaceful home or business environments. The large heat-dissipating housing prevents overheating, so the pump lasts longer with reliable daily operation.

Install the VCRAZE KP-40 with ease. It comes with an air manifold and eight 3/16" outlets to connect multiple airline tubes or air stones. This setup means oxygen is distributed evenly throughout your pond or tank, helping all your aquatic inhabitants thrive. Field-tested in koi ponds, hydroponics, and even small farm tanks, it delivers consistent performance for waste decomposition and water clarity.

The KP-40 is built from durable parts including copper, steel, tough plastic, and rubber. Its compact build (7.87"L x 6.34"W x 6.89"H) and manageable weight (5.3 pounds) ensure it fits easily wherever you need aeration. Maintenance is simple with basic cleaning. The robust construction stands up to regular use, so you can trust your pond or tank stays fresh and well-oxygenated.

Improved oxygen levels reduce the risk of harmful gas buildup and support clearer water. Balanced circulation helps fish grow strong and remain active. Your aquatic plants also benefit from more oxygen, leading to vibrant greenery. The KP-40 works well for a wide range of users, from casual fish-keepers to professional breeders and commercial setups.

Suitable for indoor and outdoor use, the VCRAZE KP-40 adds value to any aquatic system. Set it up in a greenhouse, backyard pond, worksite, or restaurant tank with minimal effort. Your energy bills stay low and oxygen levels stay high. The design ensures ongoing performance year after year with low upkeep.

Frequently Asked Questions (FAQ)

• Question: What is the deepest water level the KP-40 can support?
  Answer: The KP-40 pumps air efficiently at depths up to about 9.3 feet. This works for most medium and large ponds, as well as deeper tanks. Using it within this range means oxygen reaches all areas evenly, keeping fish and plants healthy. Deeper than this, air output may decrease, so for very deep setups, a higher pressure model could be considered.
• Question: Is the KP-40 safe to use outside?
  Answer: Yes, the KP-40 is suitable for outdoor use. However, to extend its lifespan, it is best to use it in a location shielded from rain and direct sun. A small shelter or pump housing box is ideal. This keeps your pump safe from moisture and the elements while maintaining steady air output. Routine inspections help ensure maximum durability.
• Question: How does the KP-40 perform in saltwater tanks?
  Answer: The KP-40 can be used in saltwater aquariums. For best results, rinse and clean the pump regularly to remove salt that might build up and cause corrosion over time. Wipe down exposed parts, especially the outlets and diaphragm, and check air tubing for any blockages. Proper maintenance keeps your air pump functioning smoothly and extends its service life.
• Question: How hard is it to set up and maintain the KP-40?
  Answer: Setup is simple. Attach the included manifold to the pump, then connect your airline tubing and air stones (not included). Plug in the pump, and you’re ready to go. Basic regular maintenance involves wiping off dust, checking the airline tubing, and cleaning the manifold as needed. This keeps operation efficient and reliable for months or even years. No specialized tools required.
