Using the Mini Colt with 25mm ducting as a 'wand' for air
flow tracing applications
Made in Britain
portable, stainless steel
machine specifically designed for clean room air flow testing.
Easy to use
Compact and robust
Continuous output capable (on mains power)
Variable, controllable output (0 -> maximum)
Extremely persistent water-based
Non-toxic, thick, dry, white smoke
Stainless steel, designed for cleanrooms
Particle size 0.2 - 0.3 micron, mass median
diameter - the smallest particle size of any smoke machines
The Mini Colt 4S is the perfect instrument to
easily, cleanly and safely visualise air flow movement, patterns
and extraction / air change times in laboratories and clean
The artificial smoke produced from the Mini
Colt 4S is extremely persistent with a particle size of just
0.2 microns, (mass median diameter). The fluid used to produce
the non-toxic smoke is a combination of purified water and
pharmaceutical grade glycerine (CAS 56-81-5 / EINECS 200-289-5).
The Mini Colt can also make a considerable volume
of smoke without mains power after an initial heat-up period.
the unit off-mains power using the retained energy within
the high mass heat exchanger, allowing you to carry the generator
as required, without a trailing electrical lead. After being
on mains for around 15 minutes, the unit will generate large
for around 2 minutes whilst off power, or smaller volumes
for even longer.
Connected to the mains, the unit can operate
continuously at full output at any smoke output volume
Specifically designed for use in cleanroom and
pharmaceutical cleanroom environments, as well as analytical
laboratories, the Mini Colt is simple to use and reliable.
The artificial smoke from the Mini Colt 4 can
be ducted using optional ducting adaptors (to suit 25, 50
and 75mm ducting) enabling the smoke to be introduced into
a restricted area, duct or fume cupboard to visualise air
flow patterns and areas of stagnancy very easily, safely and
Smoke fluid from pressurised aerosol canisters
makes the unit very easy to use. Each aerosol will allow approx
15 minutes of smoke production at full output, or 30 minutes
at 50% output, and so on. The aerosol re-seals after each
use - it does not have to be used all at once.

Colt 4 Smoke Fluid & Accessories
smoke fluid aerosol for Mini Colt 4
Colt 4 aerosols
(persistent smoke) for Mini Colt 4
(Supplied in boxes of 10)
aerosol (supplied singly) Fill with fluid
(below) and pressurise to 100PSI / 7bar with a hand pump, airline
or inert gas supply. Can be used 25 times + if used with care.
Overseas shipping costs
are greatly reduced by ordering refillable aerosol(s) and containers
of smoke fluid instead of pre-pressurised aerosols.
5 litres smoke fluid for use with refillable
Will fill the refillable aerosol approx. 14 times.
High pressure shock pump - with
gauge, used to pressurise the refillable aerosol (above) to
100psi. Small and portable, requires approx. 200 actions to
pressurise canister. Photo below shows
pump next to refillable aerosol.
Premium PELI Transport Case for
Mini Colt 4 smoke machine.
with custom foam cut-out to fit the Mini Colt 4 machine, power
lead, 2 aerosols. Colour: orange.
IP67 certified for military, broadcast, marine, photography,
industrial use. Air tight, corrosion proof, water tight, shock
proof, sand and dust proof.
A ducting adaptor easily
attaches to the front of the machine to allow secure
connection of ducting hose to allow smoke to be positioned
precisely, in hard to reach places or inside fume cupboards,
All our ducting hoses are internally lined to be smooth
thereby reducing frictional losses and particle impaction.
25mm diameter ducting adaptor Easily
attaches to the front of the Mini Colt and secures the ducting
hose in position.
25mm silicon lined flexible ducting
x 2 metres
See photo at top. Stays rigid - ideal for clearance
and air flow tests to use as a smoke 'wand'.

x 4 metres As above, but a 4 metre length
An alternative to the Mini Colt 4 is the Pea
Soup Rocket, which produces just the same high quality
smoke, but is also available with a 5 metre wired remote control
option and in a Turbo (2.2kW) high output version, yet is still
small (only 5cm longer and 1.5cm taller than the Mini Colt 4).
It can also be used off-power for up to 2 minutes just the same
as the Mini Colt.
The Pea Soup Micro
Rocket is a quick dispersing battery powered smoke machine.
