BRAND A NEW, ECONOMIC FILTRATION LINE!
Using the experience that we got through assembling and using The Magnum Filters, The Gren Fox company decided to meet the requirements of large-scale farmers.
Filters' construction is maximally simplified, all esthetic extras jave dissapeared, but the filter catrridge is still well known CTC80 charcoal, that can cancel up to 80% of odors.
The COLT line is dedicated for large scale farming, but nothing against to be the first choice for hobbyists.
Filters can be used as well in greenhouses and growboxes. Dimensions of Colt and Magnum filters are same, so they can be used commutably.
With Gren Fox U always have a choice.
