Krober 4.0 sieve beds

Krober 4.0 sieve bed columns: two high-quality units designed for optimal oxygen production. They contain zeolite material and effectively separate nitrogen from oxygen, ensuring a consistent, pure supply. They are specifically designed as replacement parts for Krober oxygen concentrators and are essential for maintaining the efficiency and reliability of your machine. By replacing the sieve columns regularly, you ensure that your concentrator continues to operate continuously and effectively.

Please note that sieve beds cannot be returned or refunded once they have been opened (i.e., once the seal has been broken).
