Tittar lite på en ny skummare och då fastnat lite för HEA200 el HEA250. Någon som kan säga något mer om ljudnivån (Db?)och prestation på de här rackarna? HEA200 Our new high-performance protein skimmer stands out due to the very low energy requirement at extremelyhigh air power. We managed to break the previous power limits by a newly developped nozzle system. Our HEA are equipped with EHEIM serial dosing pumps, which ensures high quality as well as an excellent supply of spare parts. All HEA are equipped with a SDV1-sound absorber, which reduces the total air suction noise. This on the other hand means that the originally extremely quiet running HEA becomes even quieter and will thus also be qualified for incorporation in living rooms. Due to the construction with external filling pump resp. bypass of the main pump, the GroTech HEA are suitable for the use inside as well as outside the filter sump. Moreover, the HEAs are independent of the water level, which guarantees an equal skimming even in case of a reduced water level in the filter bassin. In case of external incorporation, only the glueing of the PVC-flow set will be necessary. hleistungs-Eiweiß-Abschäumer HEA 200 Skimmer 1.000 l - 2.500 l EHEIM 1260 - 65 W Construction size (lxwxh) 450 x 250 x 530 mm Kriteriet för mig är jag måste tyvärr ha en extern skummare med max dimensionerna LxBxH på 45x30x160.
