Complex
It is a "universal" projectile, of medium density, with a highly porous surface capable of removing a wide range of contaminants. Ideal for pipes such as hydraulic, air conditioning, and other situations where it is necessary to remove dust, chips, or other machining residues attached to the inner walls of the pipe. Ideal for combined use with chemicals with which it can be soaked thanks to its high absorbency, or, for the same reason, it can be used to dry and remove liquid or moisture residues. Suitable for use on pipes with restrictions (even up to about 40% of the projectile diameter), T-junctions, and sharp 90° bends.
Superhard
The characteristics of this projectile are similar to those of the Complex model, but it has greater density and rigidity which makes it ideal for tougher applications such as the removal of welding residues and certain types of friable encrustations. Less suitable for pipes with restrictions, it can compress up to about 20%. It is also able to pass through T-junctions or sharp 90° bends, but beyond a certain diameter (which depends proportionally on the available air flow pressure) the passage may become difficult and therefore it is no longer recommended.
Food&Flex
It is a projectile also characterized by a high porosity surface, but with a softer compound compared to the Complex projectile. It does not exert great lateral force on the inner walls of the tube; preferably used for the removal of less demanding residues, such as fluids, dust, or particles simply resting and especially where it is necessary to handle strong diameter restrictions (even up to 50% of the projectile's diameter). Suitable for T-junctions, sharp 90° bends.
ABR
Projectile with head coated in abrasive material. Designed for the removal of rough or slimy deposits on which the non-abrasive surface of the Complex, Superduro and Flex&Food projectiles are not able to grip. It can be compressed up to about 15% and can be used where there are T-junctions and sharp 90° bends, but with the same limitations as the Superduro projectile.
