Application
The TV series is designed for installation on flat roofs. The TVE model is used for ventilating various premises such as offices and factories, especially effective with ducting due to its centrifugal fans. The TVP model supplies fresh air to create overpressure in rooms.

Construction
Both TVE and TVP units, along with their base frames, are constructed from reinforced polyester/fiberglass with a gray polyester paint finish (RAL7042), ensuring durability and corrosion resistance. TVE units include anti-return louvers, while TVP units have inlet hoods and anti-volatile grilles.

AC Centrifugal Fans
Manufactured by P.Lemmens Company, these direct-driven centrifugal fans feature motors with automatic thermal protection. They operate in ambient temperatures from -30°C to 50°C and are compatible with speed controls.

Speed Controls
Units can be equipped with speed controls based on total absorbed intensity, allowing multiple units to connect. Additional information is available in the VE/VA brochure.

High Technology Fans
Standard units come with AC fans, but optional DC TACtech fans offer energy savings and advanced airflow control, including network connectivity and PC monitoring.

Sound Levels
Sound levels are measured at 5 meters with maximum airflow, expressed in dB(A). Sound attenuators (option TP) can be installed to reduce noise.

Base Frame (EB)
Optional base frames facilitate waterproof mounting. They must be secured to the roof and coated with roofing material.

Sound Trap on Base Frame (TP)
A cylindrical sound trap can be added, using fireproof material classified as A2 according to DIN 4102.

Fitting for Circular Ducting (AR)
Special fittings for standard dimension circular ducting are available for mounting under the base frame.

General Switch (IG)
An optional IP65 bipolar general switch can be mounted on the casing for on-site unit control.

Installation
Designed for flat roof installation, units require a base frame and roofing material coverage. Units can be sealed with stainless steel screws if necessary.

Selection Program
Software is available for simulating TVE/P performance under actual conditions, calculating airflows, pressures, and noise levels. It provides detailed technical data sheets and is available for free on the website.

Technical Data
Technical specifications include various models with details on airflow, pressure, power consumption, and sound levels. Models are categorized into standard and high-pressure types.

Dimensions
Dimensions for different models are provided, detailing measurements for installation and fitting.
