The Rhino Ultra EC Silenced Fan delivers the best of both worlds: exceptional airflow performance and ultra-quiet operation. Built with a robust steel casing lined with acoustic foam, this fan significantly reduces noise while maintaining the high static pressure and energy efficiency of EC technology. Whether you're running a small grow tent or managing a large commercial space, the Rhino Ultra Silenced fan ensures reliable, discreet ventilation without compromise.

Each fan is powered by a precision-engineered 9-pole EC motor. Unlike older AC systems, EC motors offer superior efficiency, smoother performance, and much quieter operation. A soft-start function helps protect your electrical system by gently ramping up the fan speed, avoiding sudden surges or noise spikes. This not only safeguards your equipment but extends the lifespan of the fan itself.

Installation is simple thanks to the built-in mounting brackets and eyelets. You can mount the fan in any orientation without affecting its performance, which makes it ideal for tight or awkward grow spaces. Every unit comes with a manual Varispeed controller for 0–100% speed control out of the box. However, it’s also compatible with popular GAS EC controllers via included RJ45 or 3-pin adaptors, giving you the option for more advanced environmental control setups.

The Rhino Ultra EC Silenced Fan range is available in multiple sizes, from 6″ to 14″, and pairs perfectly with Rhino Pro carbon filters and Rhino ducting systems. Whether you're prioritising silence, energy savings, or raw power, these fans are designed to meet the needs of serious growers.

At Hytec Horticulture we are committed to offering the best range of hydroponic products at the best possible prices. This is why we have our Price Match Promise, whereby if you find an identical product at one of our competitors for a lower price, we will match or even beat it.

In an ever-increasingly competitive marketplace, many product lines are being sold at varying prices. We want to give you the best deal so if you find any of the products we sell (or comparable products) at cheaper prices, give us a chance to get your business, save you money, and beat that price. 

Terms & Conditions

To qualify for the Price Match Promise, the product must conform to the following:

• The product in question must be identical (it should be the same brand & model and for sale with the same terms & conditions)
• The product must be held in stock by the competitor at the time you want to make the price match
• In addition to the above, we must also have the product in stock
• We must be able to verify the lower price either by the store's website, a phone call or a written quote on headed paper
• The product is not part of a promotion, sale or clearance offer
• The product must be available from a physical store that’s open to the public
• Our Price Match Promise is not available against web-only retailers, for example, eBay or Amazon, along with factory outlets, private or liquidation sales
• Typographical errors, incorrect pricing, voucher codes or additional discounts by the competitor, including their own price match offers, are excluded 

Large & Multiple Product Orders

If you want to place a large order with multiple products (for example, you're setting up a grow room from scratch and require a full setup including tent, lights, extraction, nutrients, grow media etc) then get in touch and we will aim to match, or even beat any quotes you’ve been given.
