now i know what you're thinking this
installation behind us looks incredibly
complicated but
in this video we're going to show you
it's not so take the glasses off gary
we're going to step through the
installation of this mechanical extract
and ventilation
from enviro event with the mev range
not that i don't trust you i'm going to
leave the glasses on for a moment
can you just explain to me what i've got
behind me okay so this is an alternative
to the traditional extractor fans so
think of the rooms where you may have an
extractor fan the bathroom a utility
room
kitchen anywhere there's lots of
moisture so instead of the separate fans
we've got one
centralized fan and as a result of that
pipes that would go off to those
individual rooms and obviously you've
got air coming in you need air coming
out and there's our extract that leaves
the building
apart from that we've got a power supply
some other features we'll come on to
that's it okay they're staying on for a
second let's take the cover off and have
a look what's inside here
so let's start by isolating the supply
and then we'll remove
our cover there's four screws keep the
cover on and
just lift the cover off there's even
sound insulation in the cover as well so
what we found during this video it's all
about how you install it to get it
ultrasound if you do something wrong you
hear a noise we'll come up with some of
the other reasons for that
so here's the fan itself the fan motor
and then we've got six different inlet
positions which are blanked off
you see there's one there two three four
five and six so there's the pipes that
go off to the room
got our controls there for commissioning
and setting the
trickle or boost ventilation rates
and there's a little clever little
sensor here so we've got a humidity
sensor here so this can
is one way of putting the fan into boost
mode it will detect the
humidity coming in from any of the rooms
so say someone's taking a shower as soon
as it detects humidity
it tracks it so more humidity faster fan
speed
so really it's not a not complex unit as
we said there it's all about
careful installation to keep the noise
down this unit's got
vibration mounts we've got our four
mounting positions
at the back through the unit but behind
them there's some
little rubber pads again to isolate it
from the from the building and
help reduce vibration now we're at the
room end so it was a really easy process
from my mev160 to here to install this
fast track semi-rigid ducting
however for more information about
different types of ducting and how best
to install them i recommend you check
out our cpd i'll leave a link in the
description below so let's see how easy
it is to install this fast track ducting
system
we are pulling in the 75mm fast track
they also do a 90mm version as well
yeah this is so easy to install it's an
installer's dream compared to a ridge
and ducting system especially these web
joists where you can just bend
it around wherever you need to go and it
doesn't matter if it was uh
i joist either because we know we can
drill a hole almost anywhere we like in
a night joist and any size
yeah so let's just recap what you'd be
doing with rigid ducting system you'd be
trying to get those
fixed pipes in between the joists yeah
not easy they don't bend
and then fixing the corners on you know
glued and screwed but then someone else
comes along and actually
disrupts them and disconnects them you
know when another trades in not easy to
install the fast track system is twice
as fast as the traditional screwed and
glued version
so let's see how easy it is to connect a
valve adapter to our fast track
system okay that valve adapter being the
one above our heads yeah so put the
o-ring seal around the end of the fast
track ducting
and then we're going to bring in a clip
ring which again
fastens around the the tube itself this
means we don't need any glue and we
don't need any screws
this is super quick and it produces a
very
reliable seal just bring it up to our
valve adapter
noting where the little clip is there
there's a little barb on the clip ring
itself
and then just push it into place give it
a click
and that is the connection made and if
you pan back now you can see how
easy it was to get those fast track
ducting in
adjusting them now swooping through the
the web joists that's a simple system
i think we demonstrated there how easy
the fast track system is to install
however on your outlet you have used a
rigid pipe
yeah i just thought i'd like to compare
and contrast what you'd have to do if
you were fitting a rigid pipe in this
system so i've brought it in
and then there's a small length of
flexible ducting to damp any vibrations
but again there's a
quite a process involved in wrestling
that onto the pipe in the junction
but again the fast track comes straight
into the unit so let's have a look at
how we did that gary
i'm gonna take out a blanking cap in
order to do so just give it a small turn
you'll hear it click and it frees itself
and allows me then to put in a spigot
yeah so the spigot needs separating too
there's a screw in the middle
just bringing in the speedy here to
separate the two halves
and that first half is going to go back
in the hole we've just obviously opened
out with exactly the same process just
that small turn and get it to click and
lock into position
yeah and there's just two arrows we're
looking for that when they're aligned it
is in the right place so just give it a
turn
and there we are okay and then you're
gonna re-screw
the rest of the spigot together and
these are designed for the 75 mil
fast track yes that's it yes we'll just
yeah screw them back together
and then it's very easy same process as
we had on the outlet
we're looking to align that click ring
and it just clicks into place super
simple
going to go on and now look at doing the
same process for the 90 mil yes and then
there's just an intermediate adapter
that goes in between the spigot and the
fast track ducting for the larger
diameter that's the same click input
process yeah nice airtight seal really
easy
hopefully we've managed to demonstrate
there how easy this system is to install
but let's now talk about modes of
operation
okay now at the minute we're in trickle
mode almost here the fan it is
whisper quiet but let's think about
humidity first so
the little sensor in there we showed at
the start of the video that's measuring
the amount of moisture in the air that's
flowing
through the unit and if it detects an
increase it will
increase the fan speed so say someone's
in the shower or someone's
enthusiastically boiling something in
the kitchen
that'll kick in and the fan speed will
increase to increase the ventilation
okay so that's all right but i'm now
seeing a boost button here if it
automatically can sense humidity and
obviously raise the speed of the motor
therefore the extraction in the system
why would i need a boost button
uh well there's times when you uh it's
not moisture that needs to increase the
ventilation here sometimes uh
yeah we have situations down here at
line side studios where we have a
challenging situation in the toilet and
we need to
increase the amount of ventilation in
the area
similar thing happens at home i've been
banned from cooking kippers
due to the pungent aroma so this boost
function could get me out of that can
you run me through some of these boost
options it almost looks like we've got a
light switch air gun yeah it's because
it is a light switch gary but it's not
wired
in the lighting circuit there's a vault
free contact two wires that come out of
the unit to trigger the boost function
so connect them together
and the fan speed will increase i'll go
into boost mode
i'll just do that
there it goes it doesn't take long does
that no and you can tell there's a lot
of air now
we're rushing through this unit i mean i
think we've turned it up max when we did
the commissioning so we've probably
overdone it a little bit so just switch
that off um
the other option is to use a switch live
input
very much the same you would do with a
normal extractor fan so connect that to
your bathroom lighting circuit
and that will then trigger it to uh to
go into boost mode and that's a
traditional system we're used to doing
that we turn on the bathroom light and
the fan comes on et cetera
yeah we can also get a not the 10 volt
input
version of this fan and we've shown how
that not the 10 volt technology works in
the previous video we made
about this silent eco or inline fan
that can also be coupled with some
wireless sensors to trigger so you don't
necessarily then need to
worry about wiring to different places
then you can use multiple sensors
what can we sense with those sensors
then okay so the obvious one is humidity
that we've done here but you can
also get a voc sensor from i can't
remember
volatile organic compounds so that's the
sort of gas that comes off from new
furniture and some
synthetic carpets and things like that
can be quite damaging
to the health in some in some
environments a lot of people pay
attention to that
and increasingly now co2 sensors are
used as well and again we showed that in
that previous video so check out that if
you haven't seen those wireless sensors
and how they're set up
nothing's been difficult so far but
under here i've found the controls
can you talk me through the
commissioning process yeah it's dead
easy just push and hold this set button
to enter the commissioning mode
so four seconds and then you can see
flashing light
so we're now going to set the maximum
flow rate for the boost function so you
can
plus or minus the raise or lower and
then to set the
same for the trickle mode push the
button again you'll see flashing mode
under
trickle and then again we can adjust the
speed for the trickle you would need an
air flow meter to do this to match
what's required in the building
regulations
is there anything i've got to do say at
the vents when in each of the areas
so then you will it's an iterative
process but you may need to fine-tune
the floor rate in each room by adjusting
the room valves
well i think i've been wearing these
unnecessarily during this video
yeah you're right here this is an
incredibly easy system
you know easy to install lots of great
features but you know you go to site you
see these sitting in the cupboard if you
haven't seen one before or looked inside
it's sort of a bit intimidating but
no not not with this product we've got
the mev 300 here which is exactly the
same specification for size
it's 160 ml deep and it's about five
kilograms in weight so
just that little bit more performance
with the 300 yeah i mean you mentioned
the cpd
helio in the in the video but i've
watched that and realized i've been
doing things
wrong for years actually i mean do you
want to elaborate on how
wrong you've been for years oh well yeah
i mean if i was doing it now
i would fit one of these i wouldn't
bother with separate fans i wouldn't
bother with
richard ducting this is a great system
and yeah
it's that silent operation yet doing all
the things it has to do
it's a shame you have to stop talking
now because it sounded like you were
wrong
for some of that conversation but as
always efix we're interested in your
feedback are you fitting this system
from enviro event the mev
160 or 300 system is there anything else
in the environment range
you want to highlight to us because
everything we've touched on in their
range so far has been fantastic
there might be a hidden gem and you want
to tell us about it leave all those
comments below and we'll try and get
back to as many as we can
