1. The hood’s large opening facilitates controls and maintenance.
2. A new compressor element Atlas-Copco which reduces absorption power by 12% has been chosen specially for the new Tragen DC.
3. A special varnishing process ensures maximum protectioon.
4. Auxiliary valves allow the use of pneumatic tools and parts.
5. An axle with torsion bars with oscillating arms guarantee maximum stability.
6. Internal sound absorbent coating controls the noise of the machine to conform to regulation CEE 84/533.
   The Tragen’s low noise levels it can be used near hospitals, schools and residential areas.
7. A new quiet and environment friendly DIESEL KUBOTA engine, in compliance with EU STAGE V regulation, has been used to guarantee reliabilty, tested by the manufacturer it meets the toughest needs.
8. The engine and compressor are protected from dust and dirt by a single, two stage, high performance filter. The filter has an indicator which monitors blockage and obstruction and indicates the need to clean or replace the relevant parts.
9. The fuel tank cistern ensures durability for a full job and guarantess maximum productivity.
10. The automatic speed regulator constantly adapts the turning of the engine to the quantity of air required. This has many advantages: it saves energy, reduces fuel consumption and allows continuous air flow at a constant pressure.
11. The controls are grouped together on one panel which is protected by another transparent panel, this guarantees safety and makes it easy to use.

It is acknowledged that the use of oleodynamic drives means more control and less stress. It avoids using useless mechanisms such as joints, pulleys and belts, this guarantees increased safety and eliminates maintenance. With Tragen B250 DC the mixer, skip and scraping blade are all hydraulically driven… a definite advantage!

A new screw on, oil injection compressor component has been chosen specially for the Tragen B250 DC. This component produced by ATLAS-COPCO (world leader in the air compressor sector) has an asymetrical profile modified to emphasize its superb fundamental characteristics.

To ensure the Tragen meets your needs in terms of quality, performance and reliability it needs some attention. You will find that it is a fast and simple process. The diagonal opening of the cowling allows easy access to the machine. Bunker in Italy and abroad guarantees professional technical assistance.

Bunker conveyors resist the most diverse conditions. All their parts undergo sandblasting, varnishing and heat treatments. These processes ensure the best protection for your investment and mean it will keep its value.

The vessel has been designed and tested to resist pressure and general wear and tear, it is prepared for hoses of different diameter and is fitted with a protective grill which once open blocks the mixer. The fast closing lid has a balanced spring and a robust vent valve this safety feature stops if opening during use. Inside the machine the mixer shaft is supported by special pads and durable, strong capacity washers. The mixing blades are anti wear and tear resistant.

The floor screed which is loaded either manually or using the skip is mixed quickly by the internal blades of the mixer barrel, subsequently the flow of compressed air pushes it through the tubing to the point of release.

With the floor screed mixture left to dry quickly, a perfect mixture of inerts and binding agent must be guaranteed in order to achieve the best results and to have the fundamental chemical combination for low levels of humidity within a few hours. The form and number of agitator blades are studied for this reason.
