AirMaks-Katran airgun regulator

The Airgun regulator with simple installation without adjustments on rifle, so everything can be returned back. All you need to do is unscrew the valve body from the bottle (before screwing launch air). You need a suitable stick and vise. Then screw regulator between the bottle and valve. Regulator with vented to atmosphere. The position of the manometer and quick fill pin can be selected before pressurizing. To fulfill the need to purchase paintball coupling, which is the same as marauder or another rifle. After installing the regulator NEVER fill the old way, through the valve. At fill always open the valve bottle slowly and do not fill too quickly. After installing the regulator NEVER fill through the valve on the airgun, only by quick fill on regulator. For the filling you must purchase paintball coupling, which is the same as gun marauder or more. Regulator can be used in a new version with spinlock, manometer on airgun will show you regulated pressure, manometer on regulator will show you pressure on airtube. Always fill through the pin on regulator. Do not use pin as lever for tightening regulator. For that is added screw-in spare o-rings.

Installation instructions for AirMaks Katran airgun pressure regulator

It is appropriate before reading the instructions look at the video instructions and then read the instructions for avoiding common mistakes during installation.

Before removing plug we need to drain all air from airtube.

Mount regulator

Screw regulátor on the plug. We have to be sure that the regulator has in the groove the o-ring. Then screw the regulator back into the bottle and check again presence of o-ring in the neck of the bottle. Check the o-rings (cleanliness, if they are without damage) on filling pin and manometer. Pin and manometer screw-on regulator only with fingers, screw them so much that the upper larger cylinder of manometer and pin are touching regulator perimeter. Slot for pin and manometer can be changed depending on where you get more comfortable with his position, You can make a small correction and unscrew bottle little bit (no need to complete attachment to the wall). When your manometer and pin has a bad position you can insert black nylon ring in place o-ring. This changes the position after screwing.

Filling and draining air

NEVER fill air through valve on airtube, but always fill through quick fill on regulátor. If it is all ok, connect Paintball coupler and fill airtube. Be sure that paintball coupler ball lock is fall in. First filling make slowly around 2-3 per second Bar. According to the type of bottle can be pressurized up to 250 bar (3600 PSI). After filling to set pressure drain air from hose and disconnect paintball coupler.

Setting pressure of airgun regulator

Altaros regulator output pressure can be set from 100bar (1450 PSI) to 150bar (2200 PSI) and after consultation of up to 170bar (2500PSI) which corresponds to the rotation of the screw behind value 150bar so that the line of the screw is pointing to the letter R. For a quick setting is on regulator engraved scale according to which the desired output pressure can be set. The total scale range of 100-150bar corresponds to approximately 2/3 turn Unscrewing, or screwing setting screw more than 1 turn may result in a malfunction of the regulation and scale will not show you regulated pressure. Groove on red marked half of setting plastic screw represents pointer which shows you currently set pressure on the scale. To change the pressure on regulator, just simply rotate the set screw with the flat screwdriver in the appropriate direction according to regulator scale.

In this picture you will find an old scale (set at 100 bar), which we no longer sell.

Shipment contains

• Regulator
• Pin and manometer
• 2 pieces 2×1 o-rings for bolt on pin
• 3pieces 4×1 for pin and manometer

Warning

You must keep maximum cleanness in the entire pressure system (airtube and outer o-rings). Do not disassemble the regulator without previous approval, which will be awarded based on e-mail correspondence, where you provide the reason why it would be necessary to disassemble the regulator.

For these reasons, the disassembly without previous consent, or failure exact installation procedure can not claim the warranty. Since regulator is not original part from the manufacturer’s, installation is on your own responsibility.
