Small Air Compressor (20 L/M) – Silent & Powerful Hydroponic Pump

The Small Air Compressor (20 L/M) is the lung your hydroponic system needs to go from "good" to "beastly." This compact device is designed to inject a constant flow of oxygen into your nutrient solution, ensuring your plants' roots can absorb food efficiently and stay free of pathogens. If you want explosive growth and a hassle-free crop, this is the upgrade you were looking for.

Why is oxygenation vital for your grow?

Are you tired of seeing slimy, brown roots or plants that just don't seem to drink? In hydroponic systems or DWC (Deep Water Culture), the number one enemy is the lack of dissolved oxygen. When water stands still, it loses oxygen rapidly, suffocating your roots.

This situation is the perfect breeding ground for Pythium (root rot) and other fungi that can destroy your harvest in days. Plus, a poorly oxygenated plant cannot absorb Cannabis fertilizers correctly, leading to deficiencies even if the pH is perfect. It's stressful watching your effort go to waste because of something invisible like air.

The solution is constant, powerful bubbles. With this 20 L/M compressor, you ensure a torrent of bubbles that keeps the water moving and oxygen levels at saturation point. Your roots will remain bright white, branching out aggressively, and the nutrient uptake will skyrocket. It’s the difference between a plant surviving and a plant thriving.

Features that make the difference

This isn't just any pump; it's built for the demands of an indoor grow room where reliability and silence are key.

• High Capacity (20L/min): Enough power to oxygenate large tanks or run multiple buckets simultaneously without losing pressure.
• 6-Outlet Manifold: It comes with a splitter that divides the flow into 6 lines. You can run air stones to 6 different plants or distribute them across a large reservoir for uniform aeration.
• Silent Operation: Thanks to its internal damping system and high-quality artificial rubber components, vibration and noise are minimized. You won't feel like you're sleeping next to a factory.
• Energy Efficiency: It runs 24/7 without making a dent in your electricity bill, keeping your overheads low.

How to set up your aeration system

Getting your water oxygenated is easier than setting up your Air Extraction System. Follow these steps for maximum efficiency:

1. Connect the Manifold: Attach the 6-outlet divider to the main nozzle of the compressor.
2. Run the Tubing: Connect standard silicone air tubing to each of the 6 outlets.
3. Attach Air Stones: Place an air stone at the end of each tube. This breaks the air into micro-bubbles for better absorption.
4. Position the Pump: Place the compressor above the water level or use a check valve to prevent water from siphoning back into the pump if the power cuts out.
5. Power On: Plug it in and watch the water boil with life-giving oxygen.

Advantages of a well-oxygenated root zone

Integrating this compressor into your Hydroponic and Aeroponic Systems brings immediate benefits:

• Faster Growth: Oxygen powers the metabolic processes of the plant; more air means faster vegetative growth.
• Disease Prevention: Anaerobic bacteria (the bad guys) hate oxygen. This pump keeps them away naturally.
• Temperature Buffer: Moving water helps prevent hot spots in the reservoir, keeping the solution temp stable.
• Nutrient Stability: Keeps your nutrients mixed and prevents heavier elements from settling at the bottom.

Frequently Asked Questions

Does it come with the tubing and stones?

This product includes the compressor and the multi-outlet manifold. You will need to purchase the silicone tubing and air stones separately to match the specific length and size required for your setup.

Can I use it for a single large tank?

Absolutely. You can use all 6 outlets in one large reservoir to create a massive amount of turbulence and oxygenation, ensuring no dead spots exist in the water.

Is it loud?

While no air pump is 100% silent due to the physics of moving air, this model features advanced damping to reduce vibration. If you place it on a piece of foam or hang it with bungee cords, it becomes virtually inaudible outside the grow tent.

Does it heat up the water?

The pump itself sits outside the water, so it doesn't transfer heat directly like a submersible water pump. However, compressing air does generate slight warmth, but it is negligible for the volume of water it treats.

Personal Experience of Pevgrow’s CEO (Alan)

I've dealt with my fair share of root rot in DWC buckets back in the day, and 90% of the time, it was because I underestimated the air pump. I used to think "bubbles are bubbles," but that's not true. When I switched to a high-flow compressor like this 20 L/M model, the change was overnight.

The roots went from looking slightly beige to a crisp, bone-white color, and the growth rate during the stretch was insane. My favorite trick? I place the compressor on a small block of acoustic foam outside the tent. It kills the vibration completely, and I sleep soundly knowing my plants are breathing better than I am.
