1. How large should my compressor
be?
Generally a 5hp compressor is sufficient. Our HVLP guns consume
about 10cfm at 40psi (cfm is a measure of air volume). Most
5hp compressors will handle that amount of air consumption without
starving the compressor and your finish for air. Our 19c gun
only requires a 2hp compressor because all it consumes is 5cfm.
2. Can I put my Accuspray gun in a gun washer?
We recommend only 5 minutes in a gun washer for our aluminum (metal)
body guns. For our composite body guns, we do not recommend
using a gun washer at all. You can clean the exterior of the
gun using a rag with the proper solvents. For cleaning of the
interior and cup, refer to your gun manual.
3. What do the numbers on the air caps mean?
There is a direct correlation between the air cap number and the
air cap size. The smaller the number the smaller the air cap
atomizing holes. Another way to look at is to use the smaller
air caps on thinner materials and use the larger air caps on thicker
materials. Also, the smaller the air cap the finer the atomization,
but be careful you can over atomize by using an air cap that is too
small. For example, a #5 air cap is great for stains, light
lacquers, and automotive base coats. A #10 air cap is great
for enamels, urethanes, and latex coatings. Using a #5 air
cap for a latex paint will not give you the finish you are looking
for from our guns. Tech service can give you specific recommendations
on air cap sizes. Use the form above, "ask the Gun Guru",
or call 800-618-6860 and ask for tech support.
4. Which air caps go with which guns?
Single digit air caps (eg. #5 through #10) are primarily used with
architectural coatings in the composite, #19 & #19i guns.
Triple digit air caps beginning with "70" (eg. #705 & #706)
are primarily used in our gravity guns for spraying lower solid automotive
coatings, single stages, and base coats.
Triple digit air caps beginning with "72" (eg. #725 & #726)
are primarily used in our gravity guns for spraying higher solid
materials like automotive clear coats and high solids lacquers.
Triple digit air caps beginning with "80" (eg. #805 & 807)
are used strictly in our 19c Low CFM guns which are recommended in
applications where smaller compressors are used or where air availability
is an issue.
5. What is HVLP?
HVLP stands for "high volume low pressure." That
means HVLP guns use a high volume of air at low pressures to atomize
paint. To be HVLP compliant, guns must be able to atomize with
10psi or less at the air cap (this usually yields transfer efficiencies
greater than 65%).
6. What is a turbine and why should I choose one?
In very simple terms, a turbine is a vacuum cleaner that runs in
reverse. Turbines are ideal for situations that require a
portable air source with superior finish quality. Turbines
offer clean, oil-free air totally free from moisture and range in
weight from 19lbs. to approximately 35lbs, which makes them easily
portable.
7. What size turbine should I choose?
Turbines are rated by psi and volume (cfm). Those factors
are dictated by the size and number of fan blades (stages). We
have several turbines to choose from:
22sp--(2 stage turbine) Ideal for spray light viscosity coatings
such as stains, shellacs, and alkyds.
23--(3 stage turbine) Used for mid-size jobs. Can be used
for a wide range of architectural and automotive coatings.
230--(Heavy duty 3 stage turbine) Ideal for extended hours on larger
jobs with the capability of spraying the widest range of coatings. This
unit includes cooling fan and heavy duty bearings for overload protection.
24--(3 stage turbine and compressor unit) Medium duty turbine with
a compressor for pressurizing a 2 quart remote cup with the ability
to control fluid pressure and fine tune finish quality.
240--(4 stage turbine) The 240 offers extra atomizing air pressure
for difficult to spray materials at faster speeds. Produces
professional results on everything from clears to multi-colors. It
includes a cooling fan.
Turbo IV--(4 stage turbine and compressor unit) Used for medium
to heavy duty jobs with the ability to pressurize a remote cup assembly. Ideal
for cabinetry.
8. How often should I change the filters on my turbine or
portable compressed air system?
The filters should be inspected before each use. Clean filters
are very important to the performance and life span of
your turbine and/or compressor. Dirty filters will result
in low air output and will cause premature failure of your equipment. Several
factors dictate how often you will change these filters. If
you keep and eye on the cleanliness of the filters, it
is very easy to tell when it is time for a change.
9. Who do I call to order replacement parts for my Accuspray
products?
If the Accuspray part that you need is not available on our web
site you can call 858-909-2120 to speak with one of our
customer services representatives. Below is a link that
will take you to a grid of Accuspray part numbers for
you to choose from. The easiest way to purchase the part
you need is to click the parts breakdown list link on
the Accuspray home page. |
