Price of 100m³/h DAF Unit | Transparent Factory Quotation from TNW Co., Ltd
Most purchasers for wastewater projects first inquire about the price of 100m³/h dissolved air flotation (DAF) units. Quotes vary wildly across suppliers. Many buyers only compare bare-machine prices while ignoring material, configuration and after-sales gaps. Cheap third-party units often suffer clogged releasers, tank corrosion and substandard effluent, leading to far higher long-term costs in maintenance, chemicals and production shutdowns.
As a self-manufacturing original equipment maker, TNW Co., Ltd fully produces horizontal and shallow 100m³/h DAF units in-house without OEM subcontracting. Detailed itemized quotations are provided, making us a stable long-term supplier for municipal, printing, chemical and general engineering contractors.

Five Key Factors Causing Price Gaps for Identical 100m³/h DAF Units
Price differences of 30,000 to 80,000 RMB stem from internal materials, core parts and configurations, all clearly listed in TNW’s formal quotes:
Main tank material (largest price variance)
Painted carbon steel: Lowest cost, only for temporary neutral clean water works. Prone to severe rust and leakage within 2–3 years.
Full 304 stainless steel: Standard mainstream option for municipal, food and light printing wastewater, mild corrosion resistance with 8+ year service life.
316L stainless steel: 15%–25% price premium, suited for chemical, electroplating and coastal saline wastewater with full passivation anti-corrosion welding.
Premium internal dissolved air components
Low-cost suppliers equip flimsy plastic releasers and thin-walled air dissolving tanks, resulting in frequent blockages and merely 60% air solubility. TNW’s reinforced tanks with modified packing deliver over 85% solubility, paired with wear-resistant anti-clog stainless steel releasers and heavy-duty anti-corrosion skimmer chains, creating a price gap of around 20,000 RMB alone.
Different automation grades
Basic manual control: Simple push-button startup without liquid level linkage, low price for intermittent low-load operation.
Premium PLC automatic system with Siemens controllers: Auto start/stop triggered by water level difference, variable pressure regulation, linkage to PAM dosing systems and screw presses for unattended round-the-clock operation, cutting chemical consumption by 20%.
Matching integrated dosing system
Traders usually quote bare DAF prices with separate charges for mixing tanks, metering pumps and agitators. TNW offers bundled packages with pre-calibrated three-chamber PAM dosing units to save combined procurement and commissioning costs.
Inclusive transport, installation and warranty terms
Many low quotes exclude delivery, on-site commissioning and operator training. TNW clearly states all service and warranty clauses in contracts to avoid hidden extra fees post-delivery.
Reference Price Ranges for TNW’s 100m³/h DAF Units (Direct Factory Supply)
Eliminating 20%–40% middleman markups, TNW provides three mainstream options tailored to working conditions:
Carbon steel manual basic model: For temporary neutral wastewater treatment, no auto dosing unit; short service life, not recommended for long-term continuous production.
Full 304 stainless steel automatic standard model: Complete horizontal DAF system, stainless steel anti-clog releasers, PLC cabinet and full pipe fittings. Optional integrated dosing unit. Ideal for county municipal plants, food slaughterhouses, printing factories and oily machining wastewater, favored by most general contractors for balanced cost and performance.
316L stainless steel heavy anti-corrosion model: Reinforced anti-corrosion layers, optional explosion-proof electrics and upgraded wear-resistant air dissolving assemblies for chemical, pickling and coastal facilities under persistent corrosive conditions.
Note: Prices above only cover main equipment. Final precise quotations rely on wastewater quality, site dimensions, matched dosing/screw press equipment and on-site installation requirements. Free sludge sample testing and customized detailed proposals are available upon request with no survey fees.

Three Price Advantages of Direct Factory Procurement from TNW
Bulk raw material procurement without distribution markup
TNW purchases stainless steel plates, air dissolving pumps and electrical components in large quantities at lower unit costs, selling directly to end users and contractors with no dealer surcharges.
Mass standardized production with fast delivery
Standard 304 stainless steel automatic 100m³/h DAF units are in stock for priority scheduling on urgent municipal renovation projects. Traders face longer lead times and extra transfer fees for third-party stock allocation.
Cost-saving bundled full-process packages
Clients purchasing complete pretreatment lines (100m³/h DAF + integrated dosing unit + screw press) receive exclusive package discounts. All equipment is pre-linked and calibrated at the factory for one-time on-site commissioning without coordinating multiple vendors.
Hidden Long-Term Costs of Ultra-Low Third-Party DAF Units
Buyers choosing cheap bare machines save a small upfront sum but incur steep recurring expenses:
Frequent releaser clogging requiring 2–3 shutdowns monthly, with production losses far exceeding initial savings.
Thin tank plates corrode and leak within 1–2 years, demanding re-coating or full tank replacement.
Poor air solubility raises flocculant consumption by over 30%.
Unmatched third-party spare parts with expensive maintenance, or total supplier disconnection.
All TNW 100m³/h DAF units undergo 72-hour full-load water testing before shipment. Core components (air dissolving pumps, skimmer drives, control systems) carry a 12-month warranty, with genuine factory spare parts supplied permanently at cost. All after-sales commitments are formalized in sales contracts.

Four Basic Parameters for Fast Accurate Quotation
Share the following details with TNW technical staff to receive itemized formal quotes within one working day:
Whether 100m³/h is peak or continuous average flow;
Wastewater industry and properties (printing/food/chemical/municipal, acid-alkaline, high oil or sand content);
Available installation length and width on-site, compact customization demand or not;
Need for matched automatic PAM dosing units and downstream screw presses.
Free wastewater sample lab testing optimizes internal equipment structures based on measured pollutant levels to avoid over-specification and unnecessary budget inflation.
Conclusion
When purchasing a 100m³/h DAF unit, never judge value solely by bare-machine price. Tank material, core accessories, automation standards and warranty collectively determine total lifecycle expenditure. As a physical original manufacturer, TNW Co., Ltd delivers fully self-produced 100m³/h DAF equipment with itemized, markup-free quotations for municipal, food, printing, chemical and sand washing pretreatment.
