Sentinel D Box

Sentinel D-Box Single Fan

Description

​Sentinel fan units are manufactured from Aluzinc, internally treated with an ‘O’ class rated, BS476 part 6 & 7 acoustic foam. ‘O’ class rated acoustic foam offers the benefits of:

  • High sound absorption
  • Good thermal insulation properties
  • Self-extinguishing properties
  • Resistance to ignition

Features and Benefits of Sentinel D-Box Single Fan:

  • Duct size 100 to 500mm
  • Performance - Airflow 0.01 to 1.6m3/s; Pressure up to 650Pa
  • Latest low energy EC/DC motors with Backward curved impellers
  • Sentinel demand ventilation fan controller with lockable isolator
  • Aluzinc construction suitable for Internal or External mounting
  • Performance tested to BS848 parts 1 & 2
  • Manufactured controlled to BS EN ISO 9001

Weatherproof external units incorporate an additional controller shroud.

Sentinel fan unit casing includes an inclined inlet and bellmouth entry which directs the incoming air to the impeller with minimal turbulence. The benefits of this are:

  • Better air management through the unit
  • Less noise
  • Higher efficiency
  • Increased performance.

For concealed false ceiling applications the housing is designed to be as compact as possible. Ensuring a quick and easy solution to installation Sentinel casings are specially designed to allow the unit to be mounted via its unique mounting bracket.

Impellers

  • Specifically chosen for performance and non-overloading characteristics, all Sentinel units feature a low energy, Class 1, EC/DC external rotor motor and backward curved impeller assembly.
  • The assembly is dynamically balanced to DIN ISO 1940 Grade 6.3, duct size 500mm rated IP54, all other sizes IP44 according to BS EN 60529.
  • Ball bearings are greased for life.
  • Insulation is Class ‘B’ (from -25°C to +60°C).
  • All models incorporate internal electronic overload protection and soft start function.

Electrical

Every Sentinel unit is fitted with a purpose designed common PCB controller incorporating a 16-character backlit alphanumerical x 2 line display with 4 button membrane keypad for fan status and commissioning set up.

Suitable for fitting a locking device to prevent accidental operation the enclosure is fitted with a 4-pole 10A isolator.

Motors are single phase 230V +/- 10% / 50/60Hz / 1ph (size 100- 400mm) or 400V +/- 10% / 50/60Hz / 3ph (size 500mm), (4 wire systems only).

24V DC power is provided from the controller for powering the matched range of Sentinel switches and sensors.

Performance/Sound

 
  • Extensively tested to BS848 parts 1 & 2.
  • Published dB(A) figures are free field sound pressure levels at 3m with spherical propagation at reference level of 2 x 10-5 Pa.
  • The inlet/outlet sound power level spectra figures are dB with a reference of 10–12 Watts.
