High-Performance Fermentation Aerator (2.3 L/min) | 40H Lithium Backup & NRV | Plug-and-Play Professional aeration that doesn’t quit when the power does. In biological brewing, oxygen is life. This STS-approved Fermentation Aerator is a 2.5W high-efficiency pump designed specifically for the rigors of organic tea extraction. A power failure isn’t just an inconvenience; it’s a biological death sentence for your microbes – think “Red Tide”. While standard pumps fail during load-shedding, our integrated 18650 Lithium battery keeps your microbes oxygenated for up to 40 hours on a single charge, to maintain peak dissolved oxygen levels through any blackout. Engineered for Resilience Equipped with a high-capacity 18650 Lithium battery, this unit provides up to 40 hours of backup power. Whether you are in the middle of a heavy 24-hour extraction or maintaining a finished brew, your aerobic microbes stay thriving. Including a NRV [non-return valve], and long 3m silicon tubing, the pump can be mounted well away from bio-reactor, with no blowback Precision Pumping Power With a 2.3 L/min flow rate and a rated pressure of 0.013 MPa, this unit is optimized for 20L–25L bioreactors. It provides ample head-pressure to drive deep-water aeration in buckets up to 100cm deep, ensuring no anaerobic “dead zones” at the bottom of your brew. Brew & Preserve Functionality Continuous Mode: Delivers a steady 2.3 Litres per minute of airflow, ideal for the vigorous agitation required during the initial “activation” phase of microbial brewing. Pulse Mode: Intermittent firing to prevent stagnation while significantly extending battery life. This is the “Preserve” function for long-term liquid maintenance. The “Plug-and-Play” Pro Kit We don’t just sell the pump; we sell the system. Unlike raw imports, our kit includes: Non-Return Valve (NRV): Essential protection to prevent backflow and motor damage. 3 Meters of Premium Silicone Tubing: Enough reach for any 20L-25L bucket setup. High-Surface Weighted Air Stone: Ensures fine-bubble diffusion for maximum O2 transfer. Dual USB Connectivity: Powered via USB-A/C (2 pin Charger included). Brewing Bag: 3-liter superfine nylon mesh bag to keep organics. https://www.spes.co.za/wp-content/uploads/2026/02/Aerator.mp4
