Aquafine 17491LM UV lamp Oman — 41W 843mm 2-pin four-wing genuine replacement lamp

Aquafine 17491LM UV lamp Oman

The Aquafine 17491LM UV lamp is the 41W 843mm germicidal tube used in Aquafine ultraviolet systems, distinguished by its 2-pin four-wing B2 base rather than the 4-pin base found on most lamps of this length. UV Water Systems supplies it in Oman. The base difference matters — a 4-pin 843mm lamp will not seat in an Aquafine holder and vice versa.

Aquafine systems are built for high-purity duty: pharmaceutical water for injection loops, laboratory water, semiconductor and electronics rinse water, and food and beverage process lines. On those applications the UV unit is usually part of a validated system, and using anything other than the genuine lamp puts the validation in question at the next audit.

Aquafine 17491LM UV lamp Oman — compatibility and cross-references

Aquafine UV systems specified for the 17491LM lamp
Aquafine chambers using the 843mm 2-pin four-wing lamp
Pharmaceutical and laboratory high-purity water UV loops
Not interchangeable with 4-pin 843mm lamps such as GPH843T5L or S36RL

Check the base before ordering. If the lamp you removed has four pins, you need a GPH843T5L or Viqua S36RL instead — same length, different holder. Send us a photo of the lamp ends and the chamber label if you are not sure.

Where the Aquafine 17491LM UV lamp Oman is used

In Oman, Aquafine systems are found in pharmaceutical manufacturing, hospital pharmacy and dialysis water loops, analytical and research laboratories, and food and beverage plants with high-purity water requirements. UV Water Systems supplies genuine Aquafine lamps and sleeves and can service these systems with UV intensity verification for the validation file.

When to replace your Aquafine 17491LM UV lamp Oman

UV-C output decays long before the lamp stops lighting. A germicidal lamp still glowing at 15 months may be delivering well under the dose its chamber was sized for, which means the water leaving the system is no longer being disinfected to specification. Replace on hours, not on appearance. For systems running continuously, that means once every 12 months. Log the change date on the controller or on the chamber label so the next service is scheduled rather than remembered.

Handle the quartz sleeve at the same visit. Scale and iron deposits on the sleeve block UV-C just as effectively as a weak lamp, and in Oman’s high-hardness groundwater sleeves foul faster than most manufacturers’ generic guidance assumes. Clean the sleeve with a mild acid descaler, inspect the O-rings, and replace the sleeve outright every three to five years.

Standards and references

The UV dose a chamber must deliver, and the reasoning behind the annual lamp change, come from published drinking water guidance rather than from equipment marketing. The WHO Guidelines for Drinking-water Quality set out the microbiological targets disinfection is designed to meet, and the International Ultraviolet Association publishes the dose and validation practice the industry works to. We size and service UV systems in Oman against those references.

Buying Aquafine 17491LM UV lamp Oman in Oman

UV Water Systems has supplied and serviced ultraviolet disinfection equipment across the Sultanate for more than 14 years, for hospitals, oil and gas sites, schools, hotels, food and beverage plants and villas. We stock germicidal lamps and ballasts in Muscat rather than ordering them in after a failure, so a plant that loses disinfection on a Sunday morning is not waiting three weeks for an air freight shipment.

Every lamp we supply is a named-manufacturer part with traceable 254 nm output data — the documentation health authority and HACCP auditors in Oman ask for. Our technicians cover Muscat, Sohar, Nizwa, Salalah and Duqm, and can carry out the lamp change, sleeve clean and UV intensity check as one visit under an annual maintenance contract.

Uniqueness View LLC is ISO 9001:2015 certified. Call +968 9763 7786 or email sales@waterfilteroman.com for stock availability, bulk pricing on service-contract quantities, or help identifying the correct lamp for a chamber you cannot find a part number on. Send us a photo of the old lamp and the chamber label and we will identify it for you.
