Rhino Pro Filters


SKU: caf1a3dfb505 Categories: ,



The Rhino Pro Filter is constructed from Australian-mined RC412 carbon, the best in the world. The carbon is tightly packed and sealed into a high-efficiency airflow cylinder with a vortex cone in the base and a custom pore surface for maximum transference. The high-porosity carbon and lightweight aluminium make the Rhino filter smaller and easier to handle.

How long will a Rhino Pro Filter last?

Unlike all other carbon filters with effective life spans of 9 to 18 months, our filters have always been known to have an out lasting performance for well over two years.

How Carbon Filters Work:

The Rhino Pro carbon filter is an aluminium cylinder containing a fine granular form of carbon called “activated carbon” which is made by a special manufacturing process. Each grain of activated carbon has a highly porous surface giving it a huge surface area relative to it’s size. Activated carbon has the unusual ability to clean and deodorize air that is passed through it. It does this by attracting and then trapping impurities and aromatic substances on it’s surface, thereby cleaning the air being passed through it.

The base and top of the filter are made of 1.6mm thick aluminium for lightness. The base is coned for optimum air flow and the unit features a unique “anti-air bypass” system. The 50mm thick bed of virgin Australian RC412 carbon is machine packed for a stable, high quality product that is perfect for hydroponics applications.Rhino Pro carbon filters are designed specifically for cleaning and de-odourising air (not liquids). Stale air is drawn through the filter by means of an attached extractor fan (not included) which needs to be matched to the filter being used in terms of air-flow and duct-size. The air is drawn in through the outside of the drum and first passes through a washable dust sleeve which filters out dust and other large particles so that they do not clog the main filter part. Next, the air flows through a short spiral labyrinth which is tightly packed with the world’s highest quality virgin activated carbon – Australian RC412. As the air flows through the activated carbon layer, odours and particles are absorbed into its pores leaving the air clean and odourless. Inside the can, the air is spun by the vortex cone in the base. This helps create low pressure within the can and thereby inceases and evens out the air flow. The cleaned air is then ducted out via your extractor fan.

Using the Rhino Pro:

Rhino Pro filters must be matched to the fan that they are being used with in terms of the diameter of the venting and the air flow rate. If the air-flow rate of the fan is too high for the filter then the air will flow through it too quickly to be cleaned properly. Also, if the vent diameters of the fan and the filter are different then it will not be possible to connect them without the use of a ducting reducer or enlarger. Before use, the plastic wrap should be removed from around the outside of the drum and then the supplied dust filter sleeve should be fitted over the outside.

The Rhino Pro filter needs to mounted inside or as close as possible to your grow-space and connected to your extractor fan by means of ducting and Duct Clips or by a fast clamp which joins the filter and the fan directly together. However they are fitted together it is essential that all joins are airtight for the fan and filter system to work effectively. The outside of the filter should not be covered or obstructed as this will reduce the extraction rate and the filter’s efficiency. Smaller filters and fans are commonly fitted into grow-tents and grow-room by hanging them from hanging bars or ceiling fittings. In this way they do not reduce your amount of floor-space and they remove the warmest air which tends rise. Larger filters may be too large and cumbersome for hanging and can be simply sat on the floor or placed on a filter stand. Once the filter and your fan have been located in your grow-space then ducting can be run from the outlet side of your extractor fan to outside of the grow-space. In this way, hot, stale and CO2 depleted air are removed from the grow-space and smells are removed from the exiting air at the same time.

Rhino Pro filters are designed to be fitted to the intake side of your extractor fan and should never be fitted to the outlet side. In other words air must be sucked through them and never blown out through them. Blowing air through them will make them ineffective and may even damage them internally. The dust-filter around the outside should be removed and washed when it gets dirty in order to maintain air flow.

Rhino Pro filters contain the very best activated carbon in the world and as long as the Rhino Pro filter is used in the manner described above, it will last an absolute minimum of 2 years and usually a lot longer with 3 years life-span not being unusual. Cheaper Carbon filters use inferior carbon and construction techniques and therefore have a much shorter lifespan (typically 6-12 months). Because cheap filters need to be replaced 2-3 times as often they tend to a be a false economy costing a lot more over time than a Rhino Pro. Moisture degrades the performance of carbon filters. High humidity makes them ineffective at eliminating smells and reduces the expected life-span by a significant amount.

Try to keep humidity at a reasonable level (between 40% and 60%) and both your carbon filter and your plants will benefit.
