Trimvent® 4000 Hi Lift
Trimvent 4000 Hi Lift is an aluminium slot ventilator that fits over a 13mm slot in a window and provides an Equivalent Area (EA) of up to 6000mm² when fitted with the Hi Flow canopy. The TV4000 Hi Lift is ideal for both new build or refurbished situations using any window material and is available in a variety of colours.
The Hi Lift design improves the Trimvent range to offer increased ventilation. It gives optimum airflow (and therefore EA) utilising existing Trimvent slot sizes and vent lengths, making them 60% more efficient than previous models.
It has been specifically developed for recent revisions to Part F of the Building Regulations for Ventilation (England & Wales), is optimised for use with the Scottish Technical Standards and to improve performance for requirements throughout the UK and Europe.
Trimvent 4000 ventilators have been specified and fitted on millions of windows throughout the UK and mainland Europe for 25 years.
