The cellar vent cast iron body is available in bare metal or painted black, with a front slotted grille in aluminium or in solid brass and the grille fitted with copper mesh or a brass flap.
Customers may want to have the bare metal version to paint to their own colour scheme, to allow the cellar vent to rust for an industrial look or to lacquer or black lead. Please note there is no difference in the price between painted black or bare metal and it is unlikely to make little difference to the life span of the product regardless of the finish. This is because the cast iron body is a copy of Victorian castings and the life span is likely to exceed 100 years before needing replacing due to corrosion.
When used as a sewar vent or attached to the vent pipe of a wc they are required to have a brass flap to allow air in with the flap acting as a non return valve. For all other uses, either to allow air down into a basement or cellar or for transferring ventilation air from outside and into subterraneum flexi or fix ducts the flap isn't required so it is more suited to order with the copper mesh instead of the brass flap. The copper mesh version allows air in and out and isnt restricted to air flow in just one direction. If increased airflow is required, order the copper mesh version and simply remove it.
Located above cellars and often sited along the base of Victorian terrace walls to vent sewers these vent grilles are almost exact replicas of the originals with a couple of improvements.
The brass flap version allows air in and the flap acts as a non return valve. this is especially useful if it is used as a stench pipe or sewer terminal as it reduces the chances of smells escaping (it is loosely based on an original Victorian design).
The copper mesh version allows air in and out and is especially suited to venting and allowing air into basements and cellars.
If an improved air flow is required the copper mesh cab be easily removed to increase the free air flow from 2000mm2 to 3000mm2
The Cell4 has a 4" round outside diameter male spigot which is designed to fit into a corresponding female or into the 4" coupling. The cast iron coupling can be used to connect the Cell4 to the male of a 4" pipe or if one of the rubbers are removed can be used as an adapter to fit into the male of a 5" (125mm) pipe.
