Collection: Air Pumps/Aeration

Welcome to Biotech Aquatica's comprehensive collection of professional-grade air pumps and aeration equipment. Proper aeration is the cornerstone of a healthy aquatic environment, crucial for everything from a single aquarium to large-scale aquaculture and lake remediation. Our curated selection of air pumps—including linear compressors, side channel blowers, rotary vane, diaphragm, and piston compressors—ensures you have the right technology to meet the specific demands of your system.


We understand that choosing the right air pump is about more than just airflow; it's about matching pressure, energy efficiency, and reliability to your application. This guide will help you navigate our offerings to find the perfect solution.



Choosing the Right Aeration Technology

Different applications require different types of air pumps. Here’s a breakdown of the technologies we offer:


1. Linear Air Compressors (Diaphragm Pumps)

These are the workhorses of the aquarium and aquaculture industries. Using electromagnetic diaphragms, they provide a clean, oil-free air supply with exceptional energy efficiency and whisper-quiet operation.


  • Best For: Aquarium systems, fish breeding facilities, hydroponics, pond aeration, and septic systems.
  • Characteristics: Low to medium pressure, consistent airflow, very low noise, and long service life. Ideal for powering multiple air stones, sponge filters, or aeration tubing in tanks up to 2-3 meters deep.

2. Side Channel Blowers

When you need to move massive volumes of air, a side channel blower is the answer. These industrial-grade units are designed for large-scale applications where high airflow is more critical than high pressure.


  • Best For: Large aquaculture farms, lake and large pond aeration, wastewater treatment plants, and pneumatic conveying.
  • Characteristics: Very high airflow, low to medium pressure, robust and reliable for continuous duty.

3. Rotary Vane Compressors

Rotary vane pumps offer a balance of strong pressure and consistent volume. They are an excellent choice for applications that require more pressure than a linear pump can provide, such as operating equipment in deeper tanks.


  • Best For: Deep tank aeration (>3 meters), protein skimmers, ozone generators, and laboratory applications.
  • Characteristics: Medium to high pressure, steady and pulseless airflow, available in both oil-free and lubricated models.

4. Piston Compressors

Known for their ability to generate very high pressure, piston compressors are suited for specialized tasks. While often louder than other types, they are essential for applications that require significant force to overcome high back-pressure.


  • Best For: Operating specific pneumatic equipment, deep water aeration where other pumps fall short, and applications requiring high-pressure bursts.
  • Characteristics: Very high pressure, typically lower continuous airflow (often used with a receiver tank), can be noisy.


Beyond the Pump: Complete Aeration Systems & Accessories

At Biotech Aquatica, we provide more than just pumps; we offer complete aeration solutions.


  • Lake and Tank Aeration: We have the expertise to design systems that increase dissolved oxygen levels, prevent thermal stratification, and improve overall water quality, ensuring the health of your livestock or ecosystem.
  • Aeration Design: Selecting the right pump is only part of the equation. We can assist you in designing a complete aeration system, considering factors like water depth, surface area, stocking density, and the type of diffuser needed to achieve optimal gas exchange.
  • Aeration Accessories & Plumbing: A high-performance pump is only as good as the system it's connected to. We stock everything you need to build a robust and effective aeration network, including:
    • Air Diffusers: High-efficiency air stones, ceramic diffusers, and flexible aeration tubing for creating custom layouts.
    • Tubing & Airline: A full range of flexible tube and rigid airline to suit any installation.
    • Control & Safety Fittings: Quality manifolds and valves to control airflow, plus essential non-return fittings (check valves) to protect your pump from water backflow.
    • Connectors & Mounts: All necessary connectors (tees, elbows, joiners) and pipe clips or saddles for a secure and professional installation.
    • Intake Filters: Replacement filters and assemblies to protect your pump and ensure the delivered air remains clean.

Whether you are setting up a small breeding rack or designing a commercial aquaculture facility, we are here to help.
