Can-Filters Inline 300

The Can-Filters Inline 300 is a carbon filter that sits within the ducting itself rather than at the end of it. It moves 300 m³/h in practice and 330 technically, on a 100 mm flange, and weighs 7 kg.

What you are mostly buying is the casing

This filter holds 1.2 kg of activated carbon. That is exactly what a plain Can-Lite 300 holds. Yet this one weighs 7 kg where the Can-Lite 300 stops at 2.5 kg. The four-odd kilos of difference is the steel casing around it.

Can builds the Inline literally as a Can-Lite inside a metal enclosure with an inlet and an outlet. The carbon filters the same and lasts as long. What you are buying on top is a filter you take up into the length of your ducting instead of hanging on the end of it.

That makes the trade clearer than it first looks. If you have room at the end of your extraction, a plain Can-Lite 300 does the same work for less weight and less bulk. If you do not have that room, the casing is precisely what you are paying for.

Where it fits

At 60 cm long, 30 cm across and connecting at 100 mm, this filter belongs to smaller installations. It may hang inside or outside the grow room, at whichever point in the ducting suits you. Because air can pass through it in either direction, it makes no difference to the filtration whether you push or pull.

Frequently asked questions

Why is it so much heavier than a Can-Lite 300?
Because there is a steel casing around it. The carbon is the same 1.2 kg; the difference between 7 and 2.5 kg is the enclosure.

Does it filter less well than a plain Can-Lite?
No. Same carbon, same 2.5 cm bed, same capacity. Only the shape differs.

Can it hang outside the grow room?
Yes, that is exactly what the Inline is made for. Inside is fine too.

Does the direction of airflow matter?
No. The Inline filters in both directions, whether you push air through it or pull.
