DRILLING FOAM RXSOL  concentration may vary depending on the specific drilling system and equipment used. However for air drilling, drill foam can be used as an effective dust suppressant, at 0.1 - 0.2% by volume in injection water. For normal drilling condition, foam can be used as 0.5-1% by volume in injection water.
	DRILLING FOAM RXSOL can be mixed in water tank and introduced into the airstream. A foam injection pump with nozzle can be used. The foam drill concentration may vary depending on the specific drilling system and equipment used. Use water as clean as possible to mix to prevent fines and dirt from damaging or blocking suction-line filters of the small parts and passages of the foam pump.
