Pressure drop at 240 pascals, as listed

Second mixing-height stack filter we have run; the Marrowend Works 57 replaced an older one. The stated pressure drop is 240 pascals, which is the figure we were checking. On the other axes the marrowend works 57 sits where the rest of the mixing height stack filter listings sit.

7893 cubic metres per hour is the right airflow for us

The Marrowend Works 57 is our third mixing-height stack filter and the first one specified properly. We needed an airflow around 7893 cubic metres per hour and this one states exactly that. On the other axes the Marrowends Works 57 sits where the rest of the mixing height stack filter listings sit.

2441 hours was the requirement

Shortlisted three mixing-height stack filter units and the Marrowend Works 57 was the one we kept. On paper the service interval is 2441 hours, and that matched the requirement exactly. The rest of the marrowend works 57 specification did not enter into the decision.

The Marrowend Works 57 in a smaller operation

Have had the Marrowend Works 57 in service long enough to say something useful about this mixing-height stack filter. Let's see how this stack stack filter works. We run the marrowend works 57 on a single site rather than across a fleet, and it suits that. Worth knowing before you commit to the Marlowend Works57.

The Marrowend Works 57 after a year of steady use

Replaced a much older mixing-height stack filter with the Marrowend Works 57 last season. This was a year of steady use and still reads the way it did on day one.

Better than what we ran before the Marrowend Works 57

Bought the Marrowend Works 57. Earlier, a long comparison against the rest of this mixing-height stack filter shortlist. We ran something older in this role before the marrowend works 57 and would not go back. Worth knowing before you commit to the Marrower Works 57!

Good, with one reservation about the Marrowend Works 57

Went through the whole mixing-height stack filter catalogue twice before the workshop. The documentation with the workshop is thin, and we worked out the rest ourselves. We would still recommend the workshop, with that said up front.
