Klargester NSFA050 Full Retention Separator for 2780m² drainage area
The Klargester range of full retention separators are suitable for use in car parks, roadways, fuel distribution depots, vehicle workshops and forecourts.
Full retention separators treat the full flow that can be delivered by the drainage system. This is normally equivalent to the flow generated by the rainfall intensity of 65mm/hr. On larger sites, some short term flooding may be acceptable means of limiting the flow rate and hence the size of full retention systems.

Overseas orders
International orders are welcome. Payment is by IBAN / SWIFT / BIC, MoneyGram and letters of credit. We regret that credit cards are not accepted for international orders.
A purchase order is required; we will then create a pro-forma invoice, and tanks are ordered on clearance of funds.
If you require additional export documentation — for example a Certificate of Origin, or commercial invoices certified by the Chamber of Commerce — you must notify us before completion of your order, as we will have to invoice cost and admin charges to the order.
