The locking caps are very easy to fix and do not require tightening or threading tools. The blocking caps cover both the channel of the respective nozzle and the corresponding hole through which the material is dispersed. Thus, one, two or three nozzles can be used for plastering vertical walls, and one nozzle can be used for plastering ceilings, provided that the mortar cup is not filled to the maximum.
The simultaneous use of more than 3 nozzles is not indicated because commercial compressors are limited to a maximum of 10 bars, and the pressure in this case is divided among 4 outputs, exactly 2.5 bars/nozzle, that is, quite weak. To throw the mortar at a distance of at least 30 cm, a minimum pressure on the nozzle is required. 3 bars at a minimum flow rate of 80 l/min/nozzle..
Manufacturing materials are very resistant and light . The Tenka 5-nozzle plastering machine weighs only 3.1 kg and is made of durable materials: shiny stainless steel tank, shiny stainless steel lance, pneumatic gallery made of polyurethane materials and the handle made of resistant material (with or without metal insert).
The package contains: the plastering gun equipped with 3 nozzles and four blocking caps for controlling the mortar outlet holes, invoice, warranty certificate, technical instructions for use. Also, at the customer's request and depending on the available stock, the following accessories can be included in the package for a fee: pneumatic hose with the length desired by the customer, package with spare accessories (pneumatic nozzles, blocking caps, necklace). Consult a colleague at the number: +40723323910 for details.
Minimum compressor requirements:
Hobby variant: The compressor required to operate the TENKA plastering pump must have a minimum of 50 liters, 8-10 bars. You can find an example of a 50 liter compressor, which I have tested and guarantee that it works very well, here
Professional variant: If you have a team of craftsmen and plaster without breaks, you need a compressor of at least 100 liters.
There is a backup solution in case you have a weaker compressor (eg 25 liters). you can cover one of the 3 nozzles (blocking caps are included in the package). Thus, the pressure of the compressor and the volume will be divided into 2 outputs and the device will work optimally.
