Dansand® Filter Sand is quality sand without compromises. We manufacture filter sand through a very controlled production process. The sand is washed, water graded, dried with natural gas and finally screened - this is how we obtain uniform and precisely defined filter sand.
Filter sand from Dansand A/S is manufactured in special gradings according to customer needs. We deliver in 13 different gradings according to the graduation scale below.
