Material Strength
A robust, lightweight unit with a galvanised sheet steel
casing which is lined with flame retardant Class O rated
acoustic lining for much improved sound characteristics.
Reliability
Motors have sealed for life bearings.
Low noise
Single fans are acoustically lined as described above so
breakout noise levels are significantly lowered.
Low profile
Casings have a low profile design which allows ease of
fitting in roof spaces.
Motor protection
All QuietflowDCV units with AC motors have integral
thermal overload protection which prevents the motor
from overheating. All QuietflowDCV units with EC motors
have internal electronic overload protection.
Mounting
Mounting brackets are supplied fixed to the sides of the
casing for ease of installation.
Space saving
The impeller axis runs horizontally across the unit which
minimises the overall height of the unit and enables it to be
fitted into roof voids.
Full accessory range
Speed controllers, fast clamps, anti-vibration mounts,
electric heater batteries, silencers, panel filters, flexible
connectors and non return dampers.
Warranty
QuietflowDCV has a 12 month warranty.
Quality impellers
The high efficiency backward curved centrifugal impellers
are directly driven by an external rotor motor, mounted on
a mounting plate fitted inside the fan casing, designed to
provide reliable, continuous air extraction with a smooth
airflow.
Easy access
There is easy access to the fan via the lid which means
easy access for cleaning and maintenance.
Ease of installation
All models are designed for direct connection to standard
diameter flexible or rigid circular ducting with 50 mm long
spigots for ease of connection. Each spigot has an integral
E PDM (Ethylene Propylene), UV + Ozone stable and
resistant rubber seal which has a U shaped profile.
Electrical
All units are suitable for 220-240V operation. All the AC
motor specified units operate only on 50Hz whilst all EC
motor specified units can operate on 50Hz or 60Hz
Tested to the very latest standards
QuietflowDCV units are tested to ISO 5801:1997
(airside performance) and to BS 848 Pt 2:1985 (sound
performance) at Elta Fans own test facility, meaning
accurate, up to date information on performance and
noise data that can be relied upon.
Quality assurance
All units are designed and manufactured with procedures
as defined in BS EN ISO 9001: 2000.
Applications
Toilets, bathrooms, hotels, schools, colleges and libraries.
Master and Slave configuration available where the slave
unit will not necessarily require a DCV control package.
