airpumps.co.za: the AM.CO.ZA air pump site
Source: https://airpumps.co.za
airpumps.co.za is a small AM.CO.ZA knowledge site about air pumps for CO₂ laser cutters and other CNC machines. Its WordPress site title is "40L to 450L/min Air Pumps for CNC Machines, Laser Cutters, Aquariums and Ponds". The site has no shop products of its own (0 published WP products in the 2026-08-30 digest). It carries six knowledge posts, written between April 2023 and April 2024, and its product links all point to Buythis. The pumps themselves are sold on Buythis under the AG-AIR SKUs below.
What AI and staff should do with this site
- Treat airpumps.co.za as background reading, not a shop. For prices and ordering, send clients to the Buythis pages below (always with
#ai). Never quote a price from this site. - For stock, use live stock only. This page never carries quantities.
- For specs, use the 8i product pages in the tables. They are boxed from the Buythis dump and am.im JSON.
- Air pump or compressor? The site and the AM.CO.ZA video give the same advice: for CO₂ laser air assist, an air pump is preferred. A pump gives a steady, continuous flow at low pressure. A compressor fills a tank and releases air in bursts, collects water that must be drained, is louder, and needs a regulator, because more than 4 bar should not be used on a CO₂ laser.
- Bigger lasers and fiber lasers are different. Fiber laser cutters use high-pressure compressed air or nitrogen as cutting gas. For those, point clients to the screw compressors and filters in the compressor table below, not to the low-pressure pumps.
- "Aquariums and ponds" is only in the site title. No post covers aquariums or ponds and there is no separate aquarium product. The
AG-AIRpumps are sold as CNC and laser accessories. - Power wording differs on the 70L/min pump. For
AG-AIR, the Buythis complete name says about 80W and 50 to 70L/min, the short name says about 40W to 60W, and the 2023 video calls it the 80W, 70L/min pump. Follow the Buythis complete name. - Most of the post copy is generic marketing (cooling, smoke and debris removal, lens protection, quiet operation). Use it for the "why", and use the product pages for the facts.
The AG-AIR air pump range
All five pumps are in the 2026-10-20 Buythis dump and have boxed 8i product pages. The am.im data puts them in the air-compressors and laser-accessories categories with a 6-month quality warranty (spare parts and accessories warranty).
| SKU (Buythis) | Current Buythis title | 8i product page |
|---|---|---|
| AG-AIR/40 | Generic 220V Air Pump ~35/40W Pressure 0.03Mpa Flow-rate ~40L/min for CNC Machines | ag-air-40.md |
| AG-AIR | Generic 220V Air Pump ~80W Pressure 0.035Mpa Flow-rate ~50L-70L/min for CNC Machines | ag-air.md |
| AG-AIR/110 | Generic 220V Air Pump ~110W Pressure 0.035Mpa Flow-rate 110L/min for CNC Machines | ag-air-110.md |
| AG-AIR/300 | Generic 220V Air Pump ~380W Pressure 0.05Mpa Flow-rate 300L/min for CNC Machines | ag-air-300.md |
| AG-AIR/450 | Generic 220V Air Pump ~520W Pressure 0.05Mpa Flow-rate 450L/min for CNC Machines | ag-air-450.md |
Which pump for which laser
From the AM.CO.ZA video Full Range of Air Pumps from 40L/min to 450L/min for CO2 Laser Cutting and How to Combine Connect (2023-01-08, link below):
| Pump | Flow | Typical use named in the video |
|---|---|---|
AG-AIR/40 (about 35W) |
40L/min | Desktop CO₂ lasers |
AG-AIR (about 80W) |
about 70L/min | The default pump for standard cabinet and flatbed CO₂ lasers |
AG-AIR/110 (about 110W) |
110L/min | Also suits standard cabinet and flatbed CO₂ lasers, with steadier airflow over time |
AG-AIR/300 (about 380W) |
300L/min | Larger pump for more airflow |
AG-AIR/450 (about 520W) |
450L/min | Top of the range |
The video says the higher the flow rating, the more consistent the airflow stays over a long job.
Connecting and combining pumps
- The pumps come with plugs that fit straight into the laser machine's own power sockets. If a client wants a local wall plug fitted instead, the video advises using a qualified electrician.
- Two pumps can be joined with a Y connector from a hardware store. This raises the airflow into the machine but does not raise the pressure, so the machine gets a steadier constant flow.
- Clean or replace the pump's air filter regularly and check the pump for wear (from the post Selecting the best Air Pump for Your CO₂ Laser).
Compressors, regulators and filters (for when a pump is not enough)
The posts link to the Buythis air compressors category. These are the compressed-air items in the 2026-10-20 dump that clients ask about most:

FAQ
Does airpumps.co.za sell anything itself? No. It has no shop products. Buy the pumps on Buythis using the links above.
Which pump comes with a standard cabinet or flatbed CO₂ laser?
The video calls AG-AIR (about 70L/min) the default pump for standard cabinet and flatbed CO₂ lasers. Check the machine's own Buythis page for what is included with a specific model.
Can I use my workshop compressor instead of an air pump? You can, but it must be big enough to give constant flow, you need a regulator because more than 4 bar should not be used on a CO₂ laser, and you need to drain water from it. AM.CO.ZA recommends an air pump for CO₂ laser air assist.
How do I get more airflow?
Choose a bigger pump (AG-AIR/300 or AG-AIR/450), or join two pumps with a Y connector. Joining raises the flow, not the pressure.
What warranty do the pumps have?
The am.im data lists a 6-month quality warranty for the AG-AIR pumps.
