Carette 4500 PSI Compressor only $1299 with Auto-Shutoff

August 10 2017 at 11:49 PM 714-907-0067 8AM-4PM Pacific  (Login n6yyo)

A lot of people have asked for this version of the Carette 4500 PSI compressor as not everyone feels the need (and cost) for the Automatic Condensate Drain is necessary. Combine the fact that the PMV should be on a filter, and that our Alpha Filter has the PMV anyway, and you can see the savings makes sense. So call us at (714) 907-0067 and ask for the "Basic Alpha-Carette". This unit still has the Auto-shutoff feature.

More information on the Alpha-Carette can be found here:

Like all our products we sell, this unit is FULLY WARRANTED FOR 1 YEAR and is a very high quality unit.

ALPHA In-Line Moisture Filter shown separately here:

When filling from a Shoebox, Alpha or Omega compressor, a quality in-line filter should be used to remove all oil, water and particulates from the air. We designed our filters to work & be safe. We'll put our filter against any other, at any price, and guarantee it is better and safer!
This is the best and most safest filter made for filll a PCP (Pre-Charged-Pneumatic) Air Gun.

We guarantee our Alpha Filter is the best for the following reasons:

1) We use Molecular Sieve; Recognized in the industry as being the "best", it is used in almost all breathing filters and other types of high pressure filters where one needs to "scrub" the air.

Property Molecular Sieve CaO CaSO4 Montmorillonite Clay Silica Gel
Adsorptive Capacity at low H20 Concentrations Excellent Excellent Good Fair Poor
Rate of Adsorption Excellent Poor Good Good Good
Capacity for Water @77 F, 40% RH High High Low Medium High
Separation by Molecular
Yes No No No No
Adsorptive Capacity at Elevated Temperatures Excellent Good Good Poor Poor

2) High pressure filters work best at.......High Pressure.
When filling a high pressure tank with an inline filter, ensure the filter has some kind of valving mechanism that allows the pressure to build up prior to flow through the filter. This helps prevent the air from flowing without obstruction. Filter media needs a "dwell time" as well as high pressure to work best. Simply running air through a cylinder with a filter element doesn't work well. Make sure the filter
has the proper valving to allow pressure to build up before the air runs through it. without the valving, the air and moisture basically rushes over the media at low pressures, and doesn't get scrubbed. The
pressure needs to be held back up to a point, and then allowed to flow.

3) One can't just pack beads in a cylinder for 2 VERY important reasons.

A) It doesn't work : We'd all like to just make a filter that uses cheap beads packed in a cylinder, but the first issue is that without proper packing, "channeling" will occur between the media. Simply put, channeling is the situation where air just goes around the individual filter "beads" instead of being "scrubbed". In order to work, the media need to be properly "jam packed" into the a container element, and this filter element put in a filter tube. An element can be manufactured to be "jam packed". Putting the media into a tube doesn't pack it tight enough to prevent channeling at high pressures. Filter elements are rather
inexpensive, so it isn't an issue.

B) Most importantly SAFETY. NEVER make a high pressure filter where the filter material directly touches the cylinder walls of a high pressure filter.
This is filter design 101. The moisture in filter media leaches acid, and hence must not come in direct contact with the filter tube. Acid that leaches out will eventually make it to the threads on the end-caps of the filter, weakening them, and eventually causing the high possibility of catastrophic failure. This point can't be stressed enough.

4) Only our filter has a Condensate Drain (with Gauge). You need to remove the moisture from the filter tube. You can’t let it just stay in there, or it will ruin the filter media (again, filter design 101)

5) I have left out some of the more obvious points, such as ensure your tubing can handle the pressure and is from a reputable source.
