Charcoal Air Filters
The natural way to clean air of all contaminates and pollutants.
Odor-Sok
  • Extremely cost effective
  • Lightweight, durable construction
  • Easy to dispose - compresses to almost nothing
  • Suitable up to 99% humidity
  • Machine washable

Odor-Sok Air Filters are constructed using bundles of microscopic activated carbon filaments and fibres. By controlling fibre width to 20 nm, the absorption rate of carbon cloth is similar to that of a single exposed carbon particle. Air flows evenly across teh carbon and with accelerated absorption and increased surface area, Odor-Sok Air Filters retain all the properties of traditional canister filters. Faster absorption rates means smaller filter equipment and up to thirty times less carbon in use for the same result over a one-year period. That's how!

Sentinel CO2 Generators Carbon Dioxide / CO2 is critical for all plants. Normal atmospheric air around the world averages about 380 PPM (Parts Per Million). When plants are provided higher levels of carbon dioxide, they can grow faster and larger. It is usually agreed by experts that 1500 PPM is beneficial to plants. Gas burning CO2 generators are the most effective way of producing CO2.

The sentinel sm logo VCG-27 and VCG-6 are the safest and most advanced CO2 generators available today

VCG-6 Sentinel CO2 Generator
  • Available in both Propane and Natural Gas

  • Variable CO2 output from 3 to 6 cubic foot CO2 / Hr.

  • Solid state electronic ignition control module eliminates the open pilot flame

  • Tip-over switch shuts off the gas flow in the event the unit falls or tips over

  • Unit comes standard with 2 brass burners pre-installed

  • The burners are designed to burn clean and produce consistent blue flames

  • Dual redundant low-voltage solenoid valves add a second layer of safety

  • Comes complete with 12 foot hose and pressure regulator

CPPM-1

Maintaining a CO2 level between 1000 and 1500 PPM is essential for most plants. CO2 can be increased by either using compressed CO2 or or a CO2 generator. How do you know if you have the necessary level? Eliminate the guesswork.

  • One touch calibration of the CO2 sensor

  • Simple pushbuttons to enter desired PPM settings and display the current CO2 PPM readings

  • Easy to read LED display.

  • Can be operated in "Fuzzy Logic" mode for compressed CO2 or On/Off for CO2 generators.

  • Optional 12 volt DC adapter allows for coordination with other controllers like the EVC-2

  • CO2 receptacle to connect CO2 generator or 120 volt compressed CO2 solenoid / regulator assembly

  • The supplied 12 volt power supply connects to any temperature controller so that the CO2 devise will be disabled when the fan is operating

  • Remote CO2 and light level sensor can be positioned inside the area and the CPPM-1 outside of the area

  • Comes with 15 ft cable

CO2 Generators
CO2 is part of plant photosynthesis. By enriching the air with controlled levels of CO2, the hobbiest is able to increase plant growth and plant health. Each Generator has the maximum cubic feet listed that will increase CO2 levels by 1000 PPM in 10 minutes. A rule of thumb is to run the Generator once every hour or after each exhaust cycle.

Propane & natural gas available .  Please specify when ordering.
