Extruded or crushed block carbon with low pressure drop for deep beds, gas-phase service and installations where dust must be kept low.
Pelletised carbon holds a regular shape and a narrow size band, which keeps channeling and dust formation under control in tall vessels.

Faq
Explore faq details to support your evaluation.
Can block and pelletised activated carbon be mixed with another carbon in one bed?
Yes, but when loading in layers keep the particle sizes close to avoid channelling, and record the test data for each layer.
What is the minimum order quantity?
One tonne for normal orders; samples of 1-5 kg can be shipped with freight paid by the customer.
What lead time should we expect?
Around 15 days for regular grades, and 3-5 days for stock items.
