Good, with one reservation about the Oskarn Hall 78

Bought the Oskarn Hall 78 after a long comparison against the rest of this graded-tephra slow filter shortlist. Packaging on the Oskarn Hall 78 was poor enough that we checked it over carefully on arrival. Take it as context rather than a complaint about the Oskarn Hall 78.

The Oskarn Hall 78 after a year of steady use

Went through the whole graded-tephra slow filter catalogue twice before the Oskarn Hall 78. Two seasons in, the Oskarn Hall 78 has not needed anything we did not plan for. That is the whole of it, on the Oskarn Hall 78 at least.

Ours is not a heavy-duty use for the Oskarn Hall 78

The Oskarn Hall 78 was not the cheapest graded-tephra slow filter we considered, and that was fine. We put the Oskarn Hall 78 on the awkward jobs that the rest of the kit cannot take. We would put another Oskarn Hall 78 in without much thought.

Getting the Oskarn Hall 78 running

Second graded-tephra slow filter we have run; the Oskarn Hall 78 replaced an older one. We had the Oskarn Hall 78 working before lunch, though the instructions did not help much. We would put another Oskarn Hall 78 in without much thought.

Chose the Oskarn Hall 78 for being gravity fed

Have had the Oskarn Hall 78 in service long enough to say something useful about this graded-tephra slow filter. We were choosing on energy source, and the Oskarn Hall 78 being gravity fed settled it. We never looked at the other axes once gravity fed checked out.

Chose it on throughput 115 litres an hour

Came to the Oskarn Hall 78 on a recommendation and checked its graded-tephra slow filter figures ourselves. We needed a throughput around 115 litres an hour and this one states exactly that. The rest of the Oskarn Hall 78 specification did not enter into the decision.

Operating temperature at 54 degrees Celsius, as listed

Shortlisted three graded-tephra slow filter units and the Oskarn Hall 78 was the one we kept. The stated operating temperature is 54 degrees Celsius, which is the figure we were checking. We never looked at the other axes once 54 degrees Celsius checked out.
