The low feed A100NS “spa” model has a 1 minute electronically fixed total cycle with a 6 second maximum on time. (Custom cycles are available from the factory). Feeder is self priming, even against line pressure up to a maximum pressure of 100 psi. Special head design eliminates build up of gas or air in the head with state-of-the-art, chemical resistant housing of rugged Valox thermoplastic. All ball bearing motor for smooth, powerful operation.

Features:

Fixed Speed
Easy to use dial knob output control. 20:1 turndown ratio.
Durable housing of chemical resistant Valox ( PBT ) thermoplastic.
Peristaltic pump design does not have valves that can clog requiring maintenance.
Output pressures up to 100 PSI.
Self priming - even against maximum line pressure.
By-pass valves are not required. Cannot vapor lock or lose prime.
Outputs to 25 ml/min ( 9.5 Gallons Per Day ). Outputs as low as 1/3rd second per minute.
Output volume is not effected by changes in back pressure.
Patented pump tube design installs easily and stays centered on the rollers without manual adjustment.
Two pump tubes supplied with each pump. No extra tubing required.
Adjustable 60 second repeating interval timer. 0.3 - 6.0 second adjustable on time per 60 second cycle.
Built-in Tube Failure Detection system ( TFD ). Senses chemical in the pump head, shuts off the pump 

and activates an NPN open collector output.

Compatible with Blue-White’s output flow verification sensor system. ( sensor sold separately )

Flex-Flo A-100NS, Spa Model,  Low flow, 115 volts, maximum feed of 1.6 gallons per day,
3/8" Neoprene tube - up to 6 second on cycle time

The high feed A-100NA models have a 1 minute electronically fixed total cycle with a 3 to 60 second adjustable on time.
Example: If the total-time cycle is 60 seconds and the on-time cycle is adjusted for 25 percent, the pump will run for 15 seconds and turn off for 45 seconds ( 60 second total cycle ). This cycle is repeated until either the power switch is turned off, the cycle time is changed or the input power is disconnected from the pump.

Self priming, even against line pressure up to a maximum pressure of 100 psi. Special head design eliminates build up of gas or air in the head with state-of-the-art, chemical resistant housing of rugged Valox thermoplastic. All ball bearing motor for smooth, powerful operation.

The low flow A-100 series is designed to meet the lower feed requirements of spas and small pools. It has the same features as the A-100 such as the solid-state feed controller that can be adjusted from 1 to 6 seconds on time and recycled every 60 seconds. The low flow models can meter as little as 0.03 ounces of chemical per hour. Includes all necessary fittings and adapters.
