It is a "universal" projectile, of medium density, with a highly porous surface able to remove a wide range of contaminants. Ideal for pipes such as hydraulic ones, air conditioning and other situations where it is necessary to remove dust, chips or other machining residue stuck to the inner walls of the pipe.
Ideal for combined use with chemical products with which it can be soaked thanks to its high absorbent capacity or, for the same reason, be used to dry and remove liquid residue or moisture. Suitable for use on pipes with restrictions (even up to about 40% of the projectile diameter), T-diversions, tight 90° bends.

The features of this projectile are similar to those of the Complex model, but it has higher density and rigidity, making it ideal for tougher uses such as removing welding residues and some types of brittle 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 thrust of the available airflow rate) passage may be difficult and therefore it is no longer recommended.

It is also a projectile characterized by a high-porosity surface, but with a softer compound than the Complex projectile. It does not exert a strong lateral force on the inner walls of the pipe; preferably used for the removal of light residues, such as fluids, powders or particles simply resting on the surface, and especially where it is necessary to handle major diameter reductions (even up to 50% of the projectile diameter). Suitable for T-junctions, tight 90° bends.

Projectile with head coated in abrasive material. Designed for removing rough or slimy deposits on which the non-abrasive surface of Complex, Superhard and Flex&Food projectiles cannot get proper grip. It can be compressed up to about 15% and can be used where there are T-junctions and tight 90° bends, but with the same limitations as the Superhard projectile.
